Choose the correct option regarding the bathing soap and washing soaps.

A
Bathing soaps are potassium salts of Long-chain fatty acids. While washing soaps are sodium salts of long-chain fatty acids.
B
Washing soaps are potassium salts of long-chain fatty acids. While bathing soaps are sodium salts of long-chain fatty acids
C
Washing soaps are usually soft. While bathing soaps are usually hard.
D
Bathing soaps are usually soft. While washing soaps are usually hard.

Solution:

Concept: We are aware that washing soaps, often known as detergents, are the sodium salts of long-chain fatty acids, whereas bathing soaps are the potassium salts of long-chain fatty acids.
Although both are regarded as surface-active agents—meaning that washing compound combines with grease and water—bath and washing soaps are distinct from one another.
Referring to the nature of the alkali used in their production, soaps have unique properties. Sodium hydroxide

N a O H

forms a "hard soap" which is used for washing, whereas, when potassium hydroxide

K O H

is used, a soft soap is formed, which is used for bathing.
Hence, the correct answers are options 1 and 4.

Solution:
