Chapter 10: Q10AE (page 229)

Find the $pH$ and the concentrations of $H_{2} {SO}_{3,} {HSO}_{3}^{-}$ and role="math" localid="1654855262945" $S {O_{3}}^{2 -}$ in each solution:
(c) $0.050 {MNa}_{2} {SO}_{3}$

Short Answer

Expert verified

The concentration of solution is $7.2 \times 10^{- 13} M$

Step by step solution

Define the formula to find ph of solution.

The $pH$ of solution can be calculated as

$[H^{+}] = \sqrt{\frac{K_{1} K_{2} (0.050) + K_{1} K_{w}}{K_{1} + (0.050)}} pH = - \log {[H^{-}]}_{y} H^{-}$

Step 2: Calculate the ph and concentration of ions.

Calculate The ph of solution

$[{SO}_{3}^{_{2 -}}] + H_{2} O ◽ {HSO}_{3}^{-} + {OH}^{-} \frac{x^{2}}{0.050 - x} K_{bl} = \frac{K_{w}}{K_{22}} = 1.49 \times 10^{- 7} [{HSO}_{3}^{_{-}}] = x = 8.6 \times 10^{- 5} M [H^{+}] = \frac{K_{w}}{x} = 1.16 \times 10^{- 10} M = pH = 9.94 n [{SO}_{3}^{2 -}] = 0.050 - x = 0.050 M [H_{2} {SO}_{3}] = \frac{[H^{+}] [{HSO}_{3}^{-}]}{K_{1}} = 7.2 \times 10^{- 13} M$

The concentration of solution is $= 7.2 \times 10^{- 13} M$
