Calculate the number of coulombs required to deposit 5.4g of Al when the electrode reaction is :
`Al^(3+) +3e^(-) to Al` [Atomic weight of Al = 27 g/mol]

Text Solution

Verified by Experts

`Al^(3+)+3e^(-)rarrAl`
For 1 mol (27g) of Al requires
`=3xx96500C`
1g of Al requires = `(3xx96500)/(27)` 5.4 g of Al requires = `(3xx96500)/(27)xx5.4`
`=57900C`
