Solution

The correct option is B $1 \times 10^{- 11}$ molar
The hydroxide ion concentration in the solution $[O H^{-}] = \frac{K_{w}}{[H^{+}]} = \frac{1 \times 10^{- 14}}{1 \times 10^{- 3}} = 10^{- 11} M$
Hence, the option (B) is correct answer.

A solution of H2SO3 is found to have a hydrogen ion concentration of 1×10−3 molar at 25oC. Find the hydroxide ion concentration in the solution.

The correct option is B 1×10−11 molarThe hydroxide ion concentration in the solution [OH−]=Kw[H+]=1×10−141×10−3=10−11MHence, the option (B) is correct answer.

The correct option is B $1 \times 10^{- 11}$ molar
The hydroxide ion concentration in the solution $[O H^{-}] = \frac{K_{w}}{[H^{+}]} = \frac{1 \times 10^{- 14}}{1 \times 10^{- 3}} = 10^{- 11} M$
Hence, the option (B) is correct answer.
