The pair(s) of ions where BOTH the ions are precipitated upon passing `H_(2)S` gas in presence of dilute HCl is (are)A. `Ba^(2+), Zn^(2+)`B. `Bi^(3+) , Fe^(3+)`C. `Cu^(2+), Pb^(2+)`D. `Hg^(2+), Bi^(3+)` |
|
Answer» Correct Answer - C::D `Cu^(2+), Pb^(2+), Hg^(2+) and Bi^(3+)` all lie in Group II of qualitative analysis and are precipitated from the solution on passing `H_(2)S` gas in the solution acidified with dilute HCl. |
