Aqueous solution of a salt when treated with \(AgNO_3\) solution gives a white precipitate, which dissolves in \(NH_4OH.\)
The ion present in the salt is:
1. \(Cl^-\)
2. \(NO_3^-\)
3. \(I^-\)
4. All the av

On adding \(KI\) solution in excess to a solution of \(CuSO_4\) we get a precipitate 'P and another liquor M. Select the correct pairs:
1. P is \(Cu_2I_2 \) and M is \(I_2\) solution
2. P is \(CuI_2 \) and M is \(I_2\) solution
3. P is \(Cu_2I_2 \) and M is \(KI_3\) solution
4. P is \(CuI_2 \) and M is \(KI_3\) solution
