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 soluiotn containing `As^(+3)`
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 soluiotn containing `As^(+3)` and `Zn^(+2)` ?
A. Solubility product of `As_(2)S_(3)` is less than that of ZnS
B. Enough `As^(+3)` are present in acidic medium
C. Zinc salt does not ionise in acidic medium
D. Solubility product changes in presence of an acid.
