SATHEE: Equilibrium Question 527

Equilibrium Question 527

Question: $H_{4} O^{+}$ of a solution is 4. The hydroxide ion concentration of the solution would be [NCERT 1981; CBSE PMT 1991; MP PMT 1994]

Options:

A) $10^{- 4}$

B) $10^{- 10}$

C) $10^{- 2}$

D) $10^{- 12}$

Show Answer

Answer:

Correct Answer: B

Solution:

pH $= 4$

$p H + p O H = 14$ ; $p O H = 14 - p H$

$p O H = 14 - 4 = 10$ ; $[O H^{-}] = 10^{- 10}$ M
