Aluminum hydroxide - chemical substancewhich is a compound of aluminum oxide with water. May be in liquid and solid states. Liquid hydroxide is an incremental transparent substance that is very poorly dissolved in water. Solid hydroxide is a crystalline substance white colorwhich has passive chemical properties and does not respond to almost any other element or compound.

Obtaining aluminum hydroxide

The preparation of aluminum hydroxide is due to the chemical exchange reaction. To do this, use an aqueous solution of ammonia and any salt of aluminum, most often aluminum chloride. Thus, a liquid substance is obtained. If a solid hydroxide is needed, a carbon dioxide is passed through the solid alkali of the tetrahydroxodacodyumuminate. Many fans of experiments are concerned about how to get aluminum hydroxide at home? To do this, it is enough to purchase the necessary reagents and chemical dishes in a specialized store.

To obtain a solid, it will also be necessary for special equipment, so it is better to stay on the liquid version. When carrying out the reaction, it is necessary to use a well-ventilated room, since one of the by-products can be a gas or a substance with a sharp smell, which can negatively affect the well-being and human health. It is worth working in special protective gloves, since most acids are chemical burns when entering the skin. It will not be superfluous to take care of the protection for the eyes in the form of special glasses. Getting Started to any case, first of all it is necessary to think about ensuring security!

Fresh-insulated aluminum hydroxide reacts with most active acids and alkalis. That is why it is used to prepare ammonium water to preserve the formed substance in its pure form. When used to obtain an acid or alkali, it is necessary to accurately calculate the proportion of the elements, otherwise, with an excess, the aluminum hydroxide interacts with the remnants of an uncomplicated base and completely dissolves in it. This is due to the high level of chemical activity of aluminum and its connections.

Basically, aluminum hydroxide is obtained from bauxite ore with a high metal oxide content. The procedure allows you to quickly and relatively cheaply separate the useful elements from the empty breed. The reactions of aluminum hydroxide with acids lead to the restoration of salts and water formation, and with alkalis - to the preparation of complex hydroxaluminum salts. The solid hydroxide by the method of oscillates is combined with solid alkalis with the formation of metalulumages.

The main properties of the substance

The physical properties of aluminum hydroxide: density - 2,423 grams per centimeter Cubic, the level of solvent in water is low, the color is white or transparent. The substance may exist in four polymorphic versions. Under the influence of low temperatures, alpha hydroxide is formed, called bayerite. Under the influence of heating, gamma hydroxide or gibbsite can be obtained. Both substances have crystalline molecular lattice with hydrogen intermolecular bond types. Two more modifications are also found - beta hydroxide or nordandard and triclinic glex. The first is obtained by calcining Bayerit or Gibbsita. It differs from the other types of triclinic, and not the monotonous structure of the crystal lattice.

Chemical properties of aluminum hydroxide: molar mass - 78 mol, in liquid state It is well soluble in active acids and alkalis, when heated decomposes, has amphoteric signs. In industry in the overwhelming majority of cases it is liquid hydroxide, since high level Chemical activity, it is easily processing and does not require the use of catalysts or special conditions for the reaction.

Amphoterity of aluminum hydroxide is manifested in the duality of its nature. This means that under various conditions, it can exhibit acidic or alkaline properties. When hydroxide takes part in the reaction as alkali, a salt is formed, in which aluminum is a positively charged cation. Speaking as an acid, aluminum hydroxide at the output also forms salt. But in this case, the metal already plays the role of a negatively charged anion. Dual nature opens up ample opportunities for the use of this chemical compound. It is used in medicine for the manufacture of drugs appointed by impaired acid-alkaline balance in the body.

Aluminum hydroxide is part of vaccines as a substance that enhances the body's immune response to an irritant. The insoluability of the precipitate of aluminum hydroxide in water allows the use of substance in water treatment purposes. The chemical compound is a very strong adsorbent, which allows you to extract a large number of harmful elements from the water.

Application in industry

The use of hydroxide in industry is associated with obtaining pure aluminum. The technological process begins with the processing of ore containing aluminum oxide, which, upon completion of the process, goes into hydroxide. The output of products in this reaction is quite high, so after completion there is almost a nude breed. Next, the decomposition of aluminum hydroxide is carried out.

The procedure does not require special conditions, since the substance is well decomposed when heated to a temperature above 180 degrees Celsius. This stage allows you to select aluminum oxide. This compound is a basic or auxiliary material for manufacture large number Industrial and household products. If it is necessary to obtain pure aluminum, the electrolysis process is used with the addition of sodium cryolate. The catalyst takes oxygen from oxide, and pure aluminum settles on the cathode.

Aluminum salts

Due to the amphoterity of aluminum hydroxide and the possibility of its existence in ortho and metaofam, there are various types of salts. Since Al (OH) 3 shows very weak acid and very weak basic properties, all types of salts in aqueous solutions are strongly susceptible to hydrolysis, as a result of which the insoluble Al (OH) 3 is ultimately formed. The presence in an aqueous solution of one or another type of aluminum salts is determined by the size of the pH of this solution.

1. Al 3+ salts with anions of strong acids (AlCl 3, Al 2 (SO 4) 3, Al (NO 3) 3, ALVR 3) exist in acidified solutions. In the neutral medium, metalulumages containing aluminum in the composition of anion ALO 2 exist in a solid state. Distributed in nature. When dissolved in water, hydroxyaluminates are converted.

What is hydroxide?

it chemical compoundwhich is formed when the interaction of oxide with water. There are three types of their varieties: acid, basic and amphoteric. The first and second are divided into groups depending on their chemical activity, properties and formulas.

What is amphoteric substances?

Amphoteric can be oxides and hydroxides. These are such substances for which the acidic and basic properties are characterized, depending on the reaction conditions used by the reagents, etc. The amphoteric oxides include two types of iron oxide, manganese oxide, lead, beryllium, zinc, and aluminum . The latter, by the way, is most often obtained from its hydroxide. The amphoteric hydroxides include hydroxide beryllium, iron, as well as aluminum hydroxide, which we today and consider in our article.

Physical properties of aluminum hydroxide

This chemical compound is a solid white substance. It does not dissolve in water.

Aluminum hydroxide - Chemical properties

As mentioned above, this is the most vivid representative of the group of amphoteric hydroxides. Depending on the reaction conditions, it may exhibit both the main and acidic properties. This substance is capable of dissolving in acids, while the salt and water is formed.

For example, if mixed with a chlorine acid is equal, then we obtain aluminum chloride with water also in the same proportions. Also, another substance with which aluminum hydroxide reacts is sodium hydroxide. This is a typical main hydroxide. If you mix in equal amounts, the substance under consideration and sodium hydroxide solution, we will get a compound called sodium tetrahydrokoxalulum. Its chemical structure contains a sodium atom, an aluminum atom, four oxygen atoms and hydrogen. However, when fusing these substances, the reaction is somewhat differently, and it is not formed this connection. As a result of this process, it is possible to obtain a sodium metalulum (in its formula, it is part of one atom of sodium and aluminum and two oxygen atoms) with water in equal proportions, provided that it is mixed by the same amount of dry sodium hydroxides and aluminum and to act on them with high temperatures. If it is mixed with sodium hydroxide in other proportions, it is possible to obtain a hexagidroxaluluminate sodium, which contains three sodium atoms, one aluminum atom and six oxygen and hydrogen. In order to formed this substance, it is necessary to mix the substance under consideration and sodium hydroxide solution in proportions 1: 3, respectively. According to the principle described above, it is possible to obtain compounds called tetrahydroxyaluminate potassium and hexagidroxyaluminate potassium. Also, the substance under consideration is subject to decomposition when exposed to very high temperatures. Due to this kind of chemical reaction, aluminum oxide is formed, which also has amphoteriness, and water. If you take 200 g of hydroxide and heat it, then we obtain 50 g of oxide and 150 g of water. In addition to peculiar chemical properties, this substance also exhibits the usual properties for all hydroxides. It enters into interaction with metals salts that have lower chemical activity than aluminum. For example, you can consider the reaction between it and copper chloride for which you need to take them in a 2: 3 ratio. At the same time, water-soluble aluminum chloride and precipitate in the form of hydroxide of the downturn in the proportions 2: 3. Also, the substance in question reacts with oxides of such metals, for example, you can take the connection of the same copper. For the reaction, aluminum hydroxide and oxide can be required in a 2: 3 ratio, resulting in obtaining aluminum oxide and copper hydroxide.

Also, this hydroxide reacts with metals salts, which have lower chemical activity than sodium, and their oxides. In the first case, the standard exchange reaction occurs. When adding to it, for example, silver chloride, sodium chloride and silver hydroxide is formed, which falls into a precipitate (the exchange reaction is feasible only if one of the substances obtained in its result will be a precipitate, gas or water). When the hydroxide is added to sodium, for example, zinc oxide, we obtain the latter and water hydroxide. However, much more specific is the reactions of this aloh hydroxide, which were described above.

For example, if you take aluminum chloride and add three times more potassium hydroxide to it, then the chemical compounds are considered in the article and three times more potassium chloride. There is also a method for producing Aloh, which provides a chemical reaction between the solution of aluminum salt and the carbonate of the base metal, for the example, take sodium. To obtain aluminum hydroxide, kitchen salt and carbon dioxide in proportions 2: 6: 3, it is necessary to mix aluminum chloride, sodium carbonate (soda) and water in a 2: 3 ratio.
