MCQ

A current of strength $2.5$ amp was passed through $CuS{O_4}$ solution for $6$ minutes $26$ seconds. The amount of copper deposited is .............. $\mathrm{g}$ (Atomic weight of $Cu = 63.5$) ($1$ faraday $=\,96500$ coulombs)

✓
$0.3175$
B
$3.175$
C
$0.635$
D
$6.35$

✓

Answer

Correct option: A.

$0.3175$

a
(a) $Q = 2.5 \times 386 = 96500\,C$

$2\,F(2 \times 96500\,C)$ deposited $Cu = 63.5\,g$

Hence $965\,C$ will deposited; $Cu = 0.3175\,gm$.
