Assertion (A): A current of 96.5 A is passed into aqueous AgNO 3 solution for 100 s. The weight of silver deposited is 10.8 g (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 :

Question

Assertion (A): A current of 96.5 A is passed into aqueous AgNO 3 solution for 100 s. The weight of silver deposited is 10.8 g (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 : (A) Both (A) and (R) are true and (R) is the correct explanation of (A) (B) Both (A) and (R) are true but ( R ) is not the correct explanation of (A) (C) (A) is true but (R) is false (D) (A) is false but (R) is true

i =96.5 A , , t=100 s w =108 Q =i t Q =96.5 × 100=9650 C ∵ 96500 coulomb deposited wt. of Ag =108 g ∴ 9650 coulomb deposited wt. of Ag =(108 × 9650/96500) So, statement A is true but R is false. R is false because mass of substance deposited is directly proportional to the quantity of clectricity.

Both (A) and (R) are true and (R) is the correct explanation of (A)

Both (A) and (R) are true but (R) is not the correct explanation of (A)

(A) is true but (R) is false

(A) is false but (R) is true

i=96.5A,,t=100s w=108 Q=itQ=96.5×100=9650C ∵96500 coulomb deposited wt. of Ag=108g ∴9650 coulomb deposited wt. of Ag =96500108×9650​ So, statement A is true but R is false. R is false because mass of substance deposited is directly proportional to the quantity of clectricity.

Both (A) and (R) are true but $(R)$ is not the correct explanation of (A)
