How does the chemical nature of washing soda help in household cleaning?

Answer and explanation

Correct answer: It is basic and helps remove grease

Washing soda is sodium carbonate decahydrate, Na2CO3·10H2O, and its aqueous solution is alkaline. Alkaline substances help loosen acidic or greasy dirt, while carbonate ions can assist cleaning by reacting with some contaminants. Thus option A is correct. It is not a strong acid, it is definitely a salt, and fragrance is not its cleaning function.
