If 50 milli ampere of current is passed through copper coulometer for 60 min, calculate the amount of copper deposited.

Text Solution

Verified by Experts

Electrical charge input `=Ixx"t coulombs"`
`=50xx10^(-3)Axx60xx60sec`
`="180 coulombs."`
The chemical reaction is, `Cu^(2+)+2e rarr Cu_((s))`
1 gm atom of copper requires 2F current
`therefore" amount of copper deposted "=(63.5g.mol^(-1)xx180C)/(2xx96500C)`
`=0.0592gm.`
