The standard electrode potential values, Eo for Al3+/Al is –1.66 V and that of Tl3+/Tl is +1.26 V. The formation of M3+ ion in solution is favourable for-
1. Al has greater tendency than Tl.
2. Tl has greater tendency than Al
3. Both have equal tendency
4. Cannot predict.
White fumes appear around the bottle of anhydrous aluminium chloride due to-
1. Formation of HCl gas
2. Formation of aluminium hydroxide
3. Formation of hydrous aluminium chloride
4. None of the above
