Chemical salts are compounds that are formed when an acid and a base react together. Stearates, Sals, Esters, Iodides, and Oleates are all examples of chemical salts. Stearates are salts or esters of stearic acid, which is a type of fatty acid. Sals are salts of sulfuric acid, which is a strong acid. Esters are organic compounds that are formed when an acid reacts with an alcohol. Iodides are salts of hydroiodic acid, which is a strong acid. Oleates are salts or esters of oleic acid, which is a type of fatty acid.
