Current Electricity Charging Discharging Of Capacitors Question 42
Question: In an electrolysis experiment, a current i passes through two different cells in series, one containing a solution of $ CuSO _{4} $ and the other a solution of $ AgNO _{3} $ . The rate of increase of the weight of the cathodes in the two cells will be
[NCERT 1972]
Options:
A) In the ratio of the densities of Cu and Ag
B) In the ratio of the at weights of Cu and Ag
C) In the ratio of half the atomic weight of Cu to the atomic weight of Ag
D) In the ratio of half the atomic weight of Cu to half the atomic weight of Ag
Show Answer
Answer:
Correct Answer: C
Solution:
As $ \frac{m _{Cu}}{m _{Ag}}=\frac{E _{Cu}}{E _{Ag}}$=
$\frac{\frac{1}{2} \text{Atomic weight}_Cu}{\text{Atomic weight}_Ag} $
