Current Electricity Ques 64
64. A steady current of $1.5 amp$ flows through a copper voltameter for 10 minutes. If the electrochemical equivalent of copper is $30 \times 10^{-5} g coulomb^{-1}$, the mass of copper deposited on the electrode will be
[2007]
(a) $0.50 g$
(b) $0.67 g$
(c) $0.27 g$
(d) $0.40 g$.
Show Answer
Answer:
Correct Answer: 64.(c)
Solution:
- (c) We have, $m=$ ZIt
where, $Z$ is the electrochemical equivalent of copper.
$\Rightarrow m=30 \times 10^{-5} \times 1.5 \times 10 \times 60$
$=0.27 gm$.
