What is the total charge present on `1.4gN^(3-)` ion?

Text Solution

Verified by Experts

Total charge 1 mol of monovalent ions = 1 faraday = 96500 C.
and that of 1 mol of trivalent ions `=3xx96500C`.
`"1.4 g of M"^(3-)" ions "-="0.1 mol of "N^(3-)" ions"`
`" "[because " atomic weight of N = 14"]`
So, total charge present on `"0.1 mol or 1.4 g N"^(3-)" ions"`
`=3xx96500xx0.1=2.895xx10^(4)C.`
