A 100.0mL dilute solution of `Ag^(+)` is electrolysed for 15.0 minutes with a current of 1.25mA and the silver is removed completely. What was the initial`[Ag^=]`?

A

`2.32xx10^(-1)M`

B

`2.32xx10^(-4)M`

C

`2.32xx10^(-5)M`

D

`1.17xx10^(-4)M`

Text Solution

Verified by Experts

The correct Answer is:
D
`m=(108)/(96500)xx1.25xx10^(-3)xx15xx60`
`(m)/(108)xx1.17xx10^(-5),[Ag^(+)]=(1.17xx10^(5))/(100)xx1000`
`=1.17xx10^(-4)M`
