The common raw material used in the preparation of soap and detergent is:
Open in App
Solution
The correct option is A sodium hydroxide
Soaps are water-soluble sodium or potassium salts of fatty acids like stearic acid. [e.g. Sodium Stearate]. Soaps are made from fats and oils, or their fatty acids, by treating them chemically with a strong alkali.
Detergents are made up of concentrated acids which react with alkalis to form salts. These salts contain long-chain molecules with an ionic sulphonate group. Hence, both require a strong alkali like NaOH.
Hence, option B is correct.
