which among the following pairs of ions cannot be separated by `H_(2)S

1.	which among the following pairs of ions cannot be separated by `H_(2)S` in the presence of dilute `HCl` ?A. `Bi^(3+) , Sn^(4+)`B. `Al^(3+), Hg^(2+)`C. `Zn^(2+), Cu^(2+)`D. `Ni^(2+), Cu^(2+)`
Answer» Correct Answer - A `Br^(3+)` and `Sn^(4+)` ions belong to the same group (group II). They cannot be separated by passing `H_(2)S` through the mixture solution in the presence of dilute HCl
