Acids, Bases and Salts: MCQs and Answers with explanation 1. Water cannot act as a) Lewis acid b) Lewis base c) Bronsted acid d) Bronsted base ... Answer is a) Explanation: Lewis acid is a an electron pair acceptor. Water has an oxygen atom as a central atom. Oxygen has two bond pairs and two lone pairs of electrons. Due to presence of these elctrons pairs, oxgen cannot accept electron pair, so, water cannot act as lewis acid. show Answer 2. pH of 0.01M HCl solution is a) 10 -2 b) 10 +2 c) 2.0 d) 1.0 ... Answer is c) Explanation: HCl is a strong acid and it is completely ionized in water. So, 0.01 M HCl soltution will produce, 0.01 M H + ions and 0.01 M Cl - ions. Hence, pH = -log[H + ] pH = -log(0.01) pH = 2 show Answer 3. Aquous solution of ammonium chloride is a) Basic b) Acidic c) Neutral d) Amphoteric ... Answer is b) Explanation: Ammonium chloride (NH 4 Cl) i...
