Calcuate the number of coulombs required to deposit 6.75g of Al when the electrode reaction is `Al^(3+) + 3e^(-) rarr Al`

Text Solution

Verified by Experts

1 mole Al (27g) required 3 mole electrons or 3F charge
27g Al require `3 xx 96500C` charge
6.75g require `= (3 xx 96500 xx 6.75)/(27)`
=72375C
