Detergents are commonly used in shampoos and cleaning products for clothes. Unlike soaps, detergents remain effective in hard water due to their chemical structure, eliminating the issues of scum formation and difficulty in foam production.

Detergents, typically sodium salts of sulphonic acids or ammonium salts with chlorides or bromides ions, have long hydrocarbon chains. The charged ends of these compounds do not form insoluble precipitates with calcium and magnesium ions, making them effective in hard ...

The reaction of soap with calcium and magnesium salts, responsible for the hardness of water, leads to scum formation and hinders foam production during bathing.

The name “glacial acetic acid” arises from the fact that pure ethanoic acid often freezes in cold climates during winter. Carboxylic acids, unlike mineral acids such as HCl, are weak acids, characterized by their incomplete ionization.
