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

Consider the following sequence of tests: \(M^{n+} ~+ HCl \rightarrow \) White precipitate \(\xrightarrow \Delta \) water soluble
The metal ion \((M^{n+})\)) can be:
A white sublimable solid, when boiled with an \(NaOH\) solution, gives a colourless gas that turns Nessler's reagent brown. The solid, on being heated with solid \(K_2Cr_2O_7\) and concentrated \(H_2SO_4,\) gives red brown vapours. The white solid can be
(a) \(NH_4I\)
(b) \(NH_4Br\)
(c) \(NH_4Cl\)
(d) \((NH_4)_2SO_4\)
1. (a), (b), (d)
2. (b) and (c)
3. (a), (b), (c)
4. None of the above
