Answer:
The Difference between the chemical composition of soaps and detergents are as follows: ... Soaps are sodium (Na) salts or Potassium (K) salts of some long chain carboxylic acids whereas detergents are ammonium or sulphurated salts or long chains of carboxylic acids (COOH).
When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the cloth. Then, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster.
soaps are not suitable for washing clothes when water is hard: Soaps, when used with hard water, does not lather or produce foam easily because of the formation of a curdy precipitate or scum. This scum is created when soaps react with the calcium and magnesium ions present in hard water.❤

Answer:
The molecule of soap constitutes sodium or potassium salts of long chain carboxylic acids. In the case of soaps the carbon chain dissolves in oil and the ionic end dissolves in water. Thus the soap molecules form structures called micelles. ... Detergents are harsh on skin as compared to soap.
