Q 1138523402.     An aqueous solution of a metal bromide `MBr_2 (0.05 M)` is saturated with `H_2S.` What is the minimum `pH` at which `MS` will precipitate?
`K_(sp)` for `MS = 6.0 × 10^-21`, conc. Of saturated `H_2S = 0.1` M and `K_1 = 10^-7` and `K_2 = 1.3 × 10^-13,` for `H_2S. `
A

`2.1`

B

`1.0`

C

`3.5`

D

`0.5`

HINT

Use formula: `K = K_1 × K_2 `
