What is the time (in sec) required for depositing all the silver present in 125 mL of 1M `AgNO_(3)` solution by passing a current of 241.25 A?

A

10

B

50

C

1000

D

100

Text Solution

Verified by Experts

The correct Answer is:
B
Wt of `AgNO_(3)`= (Molarity `xx` Mwt `xx` V)`/1000` =`(1 xx 108 xx 125)/1000`96500C current is required to deposit 108g of Ag
Quantity of current required to deposit 13.5g of Ag,
`Q= (96,500 xx 13.5)/108`Q=It
`implies t=Q/I=12062.5/241.25=50 sec`
