Out of `Cu^(2+),Ni^(2+),Co^(2+)` and `Mn^(2+)` those dissolved in dil. HCL only one gives a precipitate when` H_(2)S` is passed. Identify the corresponding one.

Out of Cu^(2+),Ni^(2+),Co^(2+) and Mn^(2+) of those that dissolve in dil HCI only one give precipitate when H_(2)S is passed. Identify the corresponding order which do not give precipitation :

The metal ion which is precipitated when H_(2)S is passed with HCl is

The metal ions which are precipitated when H_(2)S gas is passed in the presence of dilute HCl is :

The metal ions which are precipitated when H_(2)S gas is passed in the presence of dilute HCl is :

The metal ion(s) which is/are not precipitated when H_(2)S is passed with HCl is

The ion not precipitated by H_(2)S in presence of HCl is :
