(i) Why bithional is added in soap ?
(ii) Why magnesium hydroxide is a better antacid than sodium bicarbonate ?
(iii) Why soaps are biodegradable whereas detergents are non-biodegradable ?
(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 the
above 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.
