Upon treatment with ammoniacal H2S{\text{H}}_{2} \text{S}, the metal ion that precipitates as a sulphide is

Options

  1. AFe(III)\text{Fe} \left(\text{III}\right)
  2. BAl(III)\text{Al} \left(\text{III}\right)
  3. CMg(II)\text{Mg} \left(\text{II}\right)
  4. DZn(II)\text{Zn} \left(\text{II}\right)

Correct answer

D. Zn(II)\text{Zn} \left(\text{II}\right)

Step-by-step solution

Among Fe3+, Al3+, Mg2+ and Zn2+, only Zn2+ is precipitated with ammoniacal H2S as ZnS.

The group III metal ions, in presence of NH4OH when H2S is bubbled through filtrate Ni2+, Co2+ and Zn2+ are precipitated as sulphides.
