SATHEE: Equilibrium Question 475

Equilibrium Question 475

Question: The concentration of hydronium $(H_{3} O^{+})$ ion in water is [CET Pune 1998]

Options:

A) Zero

B) $1 \times 10^{7}, g m i o n / l i t r e$

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

D) $1 \times 10^{- 7}, g m i o n / l i t r e$

Show Answer

Answer:

Correct Answer: D

Solution:

$H_{3} O^{+}$ ⇌ $O H^{-} + H_{2}$

$p O H + p H = 14$ ; $7 + 7 = 14$ ; $[H^{+}] + [O H^{-}] = 10^{- 14}$

$10^{- 7} + 10^{- 7} = 10^{- 14}$ ; $[O H^{-}] = 10^{- 7}$ gm ion/l.
