Answer 1

Answer #1

Q22. Correct option is : (B) 13.26

Q23. Correct option is : (B) C₉H₇N (aq) + H₂O (l) $\rightleftharpoons$ C₉H₇NH⁺ (aq) + OH^- (aq)

Q24. Correct option is : (A) 1.8 x 10^-6

Explanation

Q22. Given : hydroxide ion concentration, [OH^-] = 0.18 M

pOH = -log[OH^-]

pOH = -log(0.18 M)

pOH = 0.74

pH = 14 - pOH

pH = 14 - 0.74

pH = 13.26
