Why only As^(+3) gets precipitated as ...

Why only `As^(+3)` gets precipitated as `As_(2) S_(3)` and not `Zn^(2+)` as ZnS when `H_(2)`S is passed through an acidic solution containing `As^(+1) and Zn^(+2)`?

A

Solubility product of `As_(2) S_(3)` is less than that of ZnSs

B

Enough `As^(+3)` are present in acidie medium

C

Zinc salt does not ionise in acidic medium

D

Solubility product changes in presence of an acid.
