Soaps are the salts of long chain fatty acids..........


A typical soap can be made from lauric acid, #H_3C-(CH_2)_10CO_2H# which can be saponified with sodium hydroxide:

#H_3C(CH_2)_10CO_2H +NaOH rarrH_3C(CH_2)_10CO_2^(-)Na^(+)#

The soap, sodium laureate, has some water solubility due to carboxylate function; the grime and grease that the soap dislodges tends to be trapped in the hydrophobic tail of the soap, which agglomerates to form micelles.

Anyway, this will be explained better in your text, so please consult it.
