JEE · NEET Previous Year Question

$The pH of 0.01 N lime water is$

Topic: JEE PYQ

Answer: C. Full step-by-step solution below.

A $13.09$
B $10$
C $12$
D $9.8$

Correct answer: C

Solution

(c) Ca (OH)_{2} \to Ca^{2 +} + 2 OH^{-} 0.01 (N) At 298 K, pH = 14 - pOH = 14 - [- log (0.01)] = 14 + log 10^{- 2} = 14 - 2 = 12
