Assertion (A) : A current of 96.5 A is passed into aqueous `AgNO_(3)` solution for 100s. The weight of silver deposited is 10.8g (at. wt. of Ag =108).
Reason (R) : The mass of a substance deposited during the electrolysis of an electrolyte is inversely proportional to the quantity of electricity passing through the electrolyte.
The correct answer is

Options

A. Both (A) and (R) are true and (R) is the correct explanation of (A)
B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
C. (A) is true but (R) is false
D. (A) is false but (R) is true

Answer

C

Explanation

Current (I) = 96.5A, Time (t) =100s, Weight of Ag (w) = 108
`Q = It = 96.5 xx100 = 9650 C`
108g of Ag is deposited by 9650 C
`therefore` Weight of Ag deposited by `9650 C = (108 xx 9650)/96500 = 10.8g`.
