$\tt \red{Soaps}$

• Soaps are potassium or sodium salts of a carboxylic acid having a long aliphatic chain attached to it.

• They are surfactants (compounds that reduce the surface tension between a liquid and another substance) and therefore help in the emulsification of oils in water.

• Soaps are generally prepared via the saponification of fats and oils.

• The carboxylate end of the soap molecule is hydrophilic whereas the hydrocarbon tail is hydrophobic.

$\tt \red{Detergents}$

• Detergents are the potassium or sodium salts of a long alkyl chain ending with a sulfonate group.

are the potassium or sodium salts of a long alkyl chain ending with a sulfonate group.They are soluble in hard water.

• This solubility is attributed to the fact that the sulfonate group does not attach itself to the ions present in hard water.

• Commonly, anionic detergents such as alkyl benzene sulfonates are used for domestic purposes.
