An aqueous solution of a metal bromide

\text{MBr}_2

(0.05 M) is saturated with

\text{H}_2\text{S}

. What is the minimum pH at which MS will precipitate?

K_{sp}

for MS

= 6.0 \times 10^{-21}

. Concentration of saturated

\text{H}_2\text{S} = 0.1\,\text{M}

;

K_1 = 10^{-7}

and

K_2 = 1.3 \times 10^{-13}

for

\text{H}_2\text{S}
