Question

How is soap related to chemistry?

Answer 1

The relation of soap with chemistry:

• Soaps are salts which are prepared by the combination of bases like alkali metal hydroxide and acids like fatty acids. Thus, they are also known as Alkali salts.
• We can also check $\mathrm{pH}$ level of soap by the litmus test. The $\mathrm{pH}$ always range for soap is $8\mathrm{or}9$.
• The structure of soap contains two major parts one is the head which is hydrophilic in nature and the other is the tail which is hydrophobic in nature. The head is water soluble while the tail is dirt soluble. Thus, clothes get cleaned.

Hence, Soap's structure, characteristics and formation are related to chemistry.
