Question

Question:An aqueous solution of PdCl₂ is electrolyzed for 48.6 seconds,and during this time 0.1064 g of Pd is depositedon the cathode. What is the average current used in theelectrolysis?

Short answer

The average current used in the electrolysis is$3.97\mathrm{A}$.

Step-by-step solution

analyzing the given data

$P{d}^{+2}+2e^{-}\to Pd$

Electrolyzed for $48.6\mathrm{s}$

Pd deposited at cathode$=0.1064\mathrm{g}$

calculating the average current used in the electrolysis

$$\begin{gathered} \mathrm{I}=\frac{0.1604\mathrm{g}}{48.6\mathrm{s}}\times \frac{1\mathrm{mol}}{106.42\mathrm{g}}\times \frac{2\mathrm{mol}}{1\mathrm{mol}\mathrm{Pd}}\times \frac{96485\mathrm{C}}{1\mathrm{mol}} \\ \mathrm{I}=3.97\mathrm{A} \end{gathered}$$

Hence, the average amount of current will be$3.97\mathrm{A}$.
