Passing `H_(2)S` gas into a mixture of `Mn^(2+), Ni^(2+), Cu^(2+)` and `Hg^(2+)` ions in an acidified aqueous solution precipitatesA. CuS and `Hg_(2)S`B. MnS and CuSC. MnS and NiSD. NiS and `Hg_(2)S` |
Answer» Correct Answer - A `H_(2)S` in acidic medium precipitates radicals of group of 2 of quantitative analysis, i.e., `Cu^(2+), Hg^(2+), ` and `Pb^(2+), Br^(3+),Cd^(2+),As^(3+),Br^(3+),Sn^(2+)` |
