Use of hydrochloric acid, sodium hydroxide sulfate and calcium hydroxide Purpose Language Description
Hydrochloric acid: important chemical products, used for metal surface rust removal, manufacturing drugs (ephedrine hydrochloride, zinc chloride), etc.; there is hydrochloric acid in human gastric juice, which can help digestion. Sulfuric acid: important chemical raw materials, used for production of chemical fertilizers, pesticides, gunpowder, dyes, smelting metals, refined petroleum and metal rust removal, etc.; concentrated sulfuric acid has water absorption...
