< Acids


Acid refers to the cations ionized in aqueous solution are all compounds of hydrogen ions, which can be divided into inorganic acids and organic acids. According to the acid-base proton theory, the substance that can release protons is collectively called acid. Acids can react with bases or alkaline oxides to form salt and water, or with certain metals to form salt and hydrogen, and the indicator can be discolored when the aqueous solution contains acids. Acids are generally corrosive.

According to the number of hydrogen ions produced by acid molecule ionization, it can be divided into monobasic acid, dicarboxylic acid and ternary acid, and according to the presence or absence of oxygen atoms in acid molecule, it can be divided into oxygenated acid and anoxic acid. So how do you identify the acid? First, the purple litmus test solution is added to the solvent, if it becomes red, it is an acid solution; second, if hydrogen is released by adding active metals such as Mg, Fe, Zn, etc., it is an acid solution.

Acid is widely used in industry, laboratory and so on. The common acids are sulfuric acid, hydrochloric acid, nitric acid and so on.
