(i) What class of drug is Ranitidine?
(ii) If water contains dissolved `Ca^(2+)` ions, out of soaps and synthetic detergents, which will you use for cleaning clothes?
(iii) Which of the following is an antiseptic? 0.2% phenol, 1 % phenol

Text Solution

Verified by Experts

(i) Ranitidine is antacid an oral drug that blocks the production of acid by acid - producing cells in the stomach.
(ii) `Ca^(2+)` Makes water hard. Therefore, soap cannot be used as it gets precipitated in hard water. In contrast, a synthetic detergents does not precipitate in hard water because its calcium salt is also soluble in water. Hence, synthetic detergents can be used for cleaning clothes in hard water.
(iii) 0.2% phenol is an antiseptic.
