Answer 1

${\bold{\blue{\underline{\red{An}\pink{sw}\green{er}\purple{:-}}}}}$

☛ Soaps:-

➥ Soaps are the sodium salts or potassium salts of the long chain carboxylic acids (fatty acids).The ionic group in soap is $\sf\:{COO}^{-}\:{Na}^{+}$

➥ Soaps are not suitable for washing purposes when the water is hard.

➥ Soaps are biodegradable.

➥ Soaps have relatively weak cleansing action.

☛ Detergents:-

➥ Detergents are the sodium salts of long chain benzene sulphonic acids or long chain alkyl hydrogensulphates.The ionic group in a detergent is $\sf\:{So_3}^{-}\:{Na}^{+}$

or $\sf\:{So_4}^{-}\:{Na}^{+}$

➥ Detergents can be used for washing even when the water is hard.

➥ Some of the detergents are not biodegradable.

➥ Detergents have a strong cleansing action.

Answer 2

SOAPS -------»

★ Soaps are consisted of COONa group attached to a fatty acid having a long alkyl chain .

★ Soaps are biodegradable as soaps are environmental friendly.

★ soaps have tendency to form sum in a hard water environment.

★ Soaps are derived from Natural sources.

★ Example of soaps :---- Sodium stearate.

DETERGENT ---------»

★ Detergent are consisted of So3Na attached to a long alkyl chain.

★ Detergent are containing a branched hydrocarbon chain and hence are non biodegradable.

★ These compounds do not form SCUM .

★ Example of Detergent :------ deoxycholic acid
