SATHEE: Equilibrium Question 446

Equilibrium Question 446

Question: The $p H$ value of $0.1 M N a O H$ solution is (when there is a given reaction $[H^{+}], [O H^{-}] = 10^{- 15}$ ) [CPMT 1997]

Options:

A) 13

B) 12

C) 11

D) 2

Show Answer

Answer:

Correct Answer: A

Solution:

$[O H^{-}] = 10^{- 1} M$ ; $p O H = 1$

$p H + p O H = 14$ ; $p H = 14 - 1 = 13$ .
