Question

A 0.25 M HNO₃ solution contains 0.020 M Zn²⁺ and 0.020 M Ni²⁺. Can bubbling H₂S through the solution separate Zn²⁺ from Ni²⁺? The [H₂S] in a saturated solution of H₂S is approximately 0.10 M. (K_spa ZnS = 1.7 × 10⁻², K_spa NiS = 3.2)

Accepted Answer

Bubbling H₂S through the solution can separate Zn²⁺ from Ni²⁺ because solid ZnS will precipitate first.

Answer

Bubbling H₂S through the solution can separate Zn²⁺ from Ni²⁺ because solid NiS will precipitate first.

Answer

Bubbling H₂S through the solution cannot separate Zn²⁺ from Ni²⁺ because no precipitate will form.
