1. Chemical equation for the reaction between aluminum hydroxide and hydrochloric acid
The reaction equation between hydrochloric acid and aluminum hydroxide is: Al(OH)3 +3HCl=AlCl3+3H2O.
In the reaction, the hydrogen ions (H+) in hydrochloric acid and the hydroxide ions (OH-) in aluminum hydroxide neutralize to form water. At the same time, the aluminum ions (Al3+) in aluminum hydroxide combine with the chloride ions (Cl-) in hydrochloric acid to form aluminum chloride.
1. What is hydrochloric acid
Hydrochloric acid is an aqueous solution of hydrogen chloride (HCl). It is a monovalent inorganic strong acid and has a wide range of industrial uses. Hydrochloric acid is a colorless and transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid (mass fraction of about 37%) is extremely volatile, so when the container containing concentrated hydrochloric acid is opened, the hydrogen chloride gas will evaporate and combine with water vapor in the air to produce small droplets of hydrochloric acid, causing acid to appear above the bottle mouth. fog.
2. What is aluminum hydroxide
The chemical formula of aluminum hydroxide is Al (OH) 3, which is aluminum hydroxide. Aluminum hydroxide can react with acids to form salt and water and can react with strong bases to form salt and water, so it is also an amphoteric hydroxide. Because it also has a certain acidity, it can also be called aluminic acid.
2. What is the reaction phenomenon between aluminum hydroxide and hydrochloric acid?
1. Aluminum hydroxide The reaction phenomenon with hydrochloric acid is: the white precipitate in the solution gradually disappears.
2. Practical use of the reaction between aluminum hydroxide and hydrochloric acid: Aluminum hydroxide is the hydroxide of aluminum. It is mainly used as a gastric acid neutralizer in medicine. It can neutralize gastric acid and be used for gastric ulcers, etc. Treatment of diseases, reacts with hydrochloric acid to produce salt and water.
