Vedclass · Answer

(B) Detergents are considered better cleansing agents than soaps because they can function effectively in both hard and soft water.Soaps react with calcium $(Ca^{2+})$ and magnesium $(Mg^{2+})$ ions present in hard water to form insoluble precipitates known as scum,which reduces their cleaning efficiency.In contrast,the charged ends of detergent molecules do not form insoluble precipitates with these ions,allowing them to maintain their cleansing action even in hard water.

Why are detergents better cleansing agents than soaps? Explain.
