Types of Salts

Normal salt

Normal salts are electrically neutral. They are formed when acids and bases neutralize, and these salts don’t have replaceable hydrogen or hydroxyl in their formula. Metallic ions replace the hydrogen ions completely. For e.g. NaCl, KNO3, CuSO4 etc.

Basic salt

Salt formed due to partial replacement of hydroxy radicals of a diacidic base or a triacidic base with an acid radical. This kind of acid consists of hydroxyl, metallic cation and anion of an acid. For e.g. basic Zinc chloride, basic magnesium chloride, ZnOHCL etc.

Acidic salt

If a polybasic acid is neutralized partly by a base, the salt formed is acidic. In other words, such salt is produced by the replacement of only a part of the acidic hydrogen of the polybasic acid by a metal. For e.g. NaHSO4, NaHS, NaHCO3 etc.

Double salt

Double salts have more than one cation or anion. They’re a crystalline salt having the composition of a mixture of two simple salts but with a different crystal structure from either. For e.g. bromlite, potassium sodium tartrate, aluminium sulfacetate etc.

Mixed salt

A mixed salt is a salt made from more than one base or acid. For e.g. sodium potassium sulphate, bleaching powder etc.

Complex salt

Salt formed due to combining a saturated solution of simple salts followed by crystallization of the solution similar to double salts. For e.g. Sodium silver cyanide, potassium mercuric iodide etc.
