(i) bithinol is added to soap to reduce the odour produced by bacterial decomposition of organic matter on the skin.

(ii)is a better antacid than sodium bicarbonate because, it is insolute and does not increase theabove neutrality.

(iii) soaps are biodegradable whereas detergents are non bio-degradable, because detergents have generally highly branched hydrocarbon chains. the side chain stops bacteria from attacking breaking the chains, hence, they are non- biodegradable while in soaps, it is not the case.
