Question

How many coulomb of electricity will be consumed when 100 mA current is passed through a solution of AgNO3 for half an hour during electrolysis

• A. 108
• B. 180
• C. 1800
• D. 18000

Answer 1

Answer: (B)

180

Answer 2

Charge passed during electrolysis = i. x. t

= $(100 \times 10^{- 3}) \times (\frac{1}{2} \times 60 \times 60) = 180C$
