When zinc rod is directly placed in copper sulphate solution:
1. The blue colour of the solution starts intensifying.
2. The solution remains electrically neutral.
3. The temperature of the solution falls.
4. The weight of the zinc rod starts increasing.
(A) | 4LiH + AlCl3 → 3LiCl + LiAlH4 |
(B) | N2O3 + 3H2O → 2H3O+ + 2NO2- |
(C) | NH4NO3 → 2H2O + N2O |
The set of metals that can show disproportionation reaction is:
1. Cu, Na, Li
2. Mg, F, Ne
3. P, Cl, S
4. Mn, Cu, Ga
