What is the definition of acid?
Acid is a general term for a class of compounds. The narrow definition of acid in chemistry is a compound in which all cations ionized in an aqueous solution are hydrogen ions. The broad definition is a substance that can accept electron pairs. Examples of acids: sulfuric acid, hydrochloric acid, nitric acid, acetic acid, etc.
What are the classifications of acids?
According to organic and inorganic, it is divided into inorganic acid and organic acid. Organic acid refers to some organic compounds with acidity. The most common organic acid is a carboxylic acid, and its acidity is derived from the carboxyl group. Sulfonic acids are also organic acids. Organic acids can react with alcohols to form esters; according to whether they contain oxygen, they are divided into oxyacids and anaerobic acids, oxyacids such as sulfuric acid, carbonic acid, anaerobic acids such as hydrochloric acid, hydrofluoric acid, etc.; according to whether it is a central atom to obtain electrons It is a strong oxidizing acid and a non-strong oxidizing acid; according to the degree of ionization of the acid in the aqueous solution, there are strong acid and weak acid. It is generally believed that strong acid is completely ionized in aqueous solution, such as hydrochloric acid and nitric acid; weak acid is partially ionized in aqueous solution, Such as acetic acid, carbonic acid.
What is the nature of chemical acid?
The properties of acids generally include water absorption, dehydration, and strong oxidizing properties. Most acids are corrosive.
