Question
The electrochemical equivalents of two substances are E1 and E2. The current that must pass to deposit the same amount at the cathodes in the same time must be in the ratio of
Options
A.E1:E2
B.E2:E1
C.(E1 − E2):E2
D.E1:(E2 − E1)
Solution
W = Z ⋅ i ⋅ t ⇒ Z ⋅ i = constant
$\therefore\frac{i_{1}}{i_{2}} = \frac{Z_{1}}{Z_{2}} = \frac{E_{2}}{E_{1}}$
