How many coulombs of electricity are c onsumed when a 100mA current is passed through a solution of `AgNO_(3)` for half an hour during an electrolysis experiment?

A

108

B

180

C

1800

D

18000

Text Solution

Verified by Experts

The correct Answer is:
B
`Q = ixxt`
`i= 100 mA = (100)/(1000) A`
`t = 30 ` min = `30 xx 60` seconds
`therefore Q = (100)/(1000) xx 30 xx 60 = 180` coulombs
