A current of 2.0 A when passed for 5 hrs through a molten slat deposits 22.2 g of metal (of atomic weight 177) The oxidation state of metal in metal salt is

Text Solution

Verified by Experts

Nitrogen exhibits `-3` state in nitride and phosphorus exhibits `-3` state in phosphide. Going down the group, the atomic size increases and metallic character also increases. Hence, the tendency to exhibit negative oxidation state decreases down the group VA
