SATHEE: Equilibrium Question 525

Equilibrium Question 525

Question: The hydrogen ion concentration of 0.001 $M N a O H$ solution is [AFMC 1983]

Options:

A) $1 \times 10^{- 2} m o l e / l i t r e$

B) $1 \times 10^{- 11} m o l e / l i t r e$

C) $1 \times 10^{- 14} m o l e / l i t r e$

D) $1 \times 10^{- 12} m o l e / l i t r e$

Show Answer

Answer:

Correct Answer: B

Solution:

0.001 M $N a O H$ means $[O H^{-}] = 10^{- 3}$ ; $p O H = 3$

$p H + p O H = 14; p H = 14 - 3$

$p H = 11$ ; $[H^{+}] = 10^{- 11} m o l e / l i t r e^{- 1}$
