Hi, At first I love to share with you this day a new and wonderful topic about acids and rules that you can enjoy
Acids and bases
Acids and bases occupy a large area in important chemical reactions. Food salt is the result of an acid compound reaction with a basal compound. Many foods contain acids, especially citric acids. They contain citric acid. The apple contains malic. Milk contains lactic. Widely used in construction, as well as in the manufacture of agricultural fertilizers.
Acid
Acid is a chemical compound, containing the hydronium group, and can be obtained from various sources. It is either plant, animal or mineral. The first two types are used in food and are human health. Mineral acids are toxic, There are two types of acids classified according to their strength, some of which is strong acid, and what is weak, and this classification depends on the degree of ionization of acid in water, the more ions broken in water, the more powerful.
Examples of Acid Acids
1-Ritek, is used in the manufacture of automotive batteries, the agricultural fertilizer industry.
2- Acetic acid, which is on two types, one resulting from the fermentation of plants such as apples, or grapes, and some industrial uses for the manufacture of industrial vinegar solution.
3- Alhidoklorett acid, produced by the stomach to digest the food.
Properties of acid solutions
1-Acid solutions are characterized by several properties, including: the conductivity of the electric current, and the stronger the acid the more its ability to deliver electricity.
2- Itagivr color with reagents such as methyl, and Alvenovthalin, and can therefore be sure of the type of solution is whether easily acidic by changing its color.
3-Strongly react with metals, producing hydrogen gas.
Rule rules
Is a chemical compound that contains the hydroxide group, and the rules of large spread, and many uses, as they dissolve in water to produce a solution based cattle, and vary the strength of this solution according to the number of decomposing it in the water ions, the more increased Alheidoad group in the water was the solution stronger.
Examples of rules
1- Sodium hydroxide is used in the soap industry.
2-Calcium hydroxide is used in construction.
3-Magnesium hydroxide, and is used in the treatment of acidity drugs.
Properties of solutions
1-Rules Alkaline solutions are characterized by several characteristics, the most important of which are:
2-Connected to the electrical current, and increase its conductivity as the number of ions dissolved in water.
3- It changes color with reagents, and can be easily detected by changing its color after adding the reagents.
Acid reaction with the base
One of the most important chemical reactions is the reaction of the acid with the base, resulting in salt and water, after the union by replacing the hydrogen ion in the acid with positive ion. Examples of salts resulting from the interaction of acid and base, the most prominent examples of sodium chloride salt, the table salt caused by the reaction of chloric acid, With sodium hydroxide.
We wish you good luck
