Question

Find the amount of silver liberated at cathode if $$0.500 A $$ of current is passed through $$AgNO_3$$ electrolyte for $$1$$ hour. Atomic weight of silver is $$107.9\,g\,mol^{-1}$$

Solution
Verified by Toppr

Atomic weight of silvenis = $$107.9g/mol$$
$$I=0.500A$$
The ECE of silver
Equivalent mass of silver,$$E_{Ag}=107.9$$ [As Ag is monoatomic]
$$Z_{Ag}=\dfrac { E }{ f } =\dfrac { 107.9 }{ 96500 } =0.001118$$
$$M=Zit=0.0011178\times 0.5\times 3600=2.01g$$
