Calculate the total charge carried by `"1.6 g of "O^(2-)` ion.

Text Solution

Verified by Experts

Charge on 1 mol monovalent ions = 1 F = 96500C
`therefore" Charge on 1 mol of bivalent ions "=2xx96500C`
Again, `"1 mol "O^(2-) " ions = 16 g "O^(2-)" ions"`
`" "[because " atomic weight of O = 16"]`
`therefore" Charge carried by 16g "O^(2-)" ions "=2xx96500C`
`therefore" Charge carried by 1.6g "O^(2-)" ions"`
`=(2xx96500xx1.6)/(16)C=19300C=1.93xx10^(4)C`
