[单选题]
Electrolysis of $Cu^{2+}$ using a current of 1A for 10s produces x mol of Cu metal.
If Q= It, how many moles of Cu metal is produced if $Cu^+$ is electrolyzed under the same conditions?
A. $x$
B. 2x
C. $\frac{x}{2}$
D. 0
参考答案: B
本题详细解析:
$Cu^+$ requires half as many electrons to form Cu as $Cu^{2+}$.
Therefore, twice as many moles of Cu can be formed by transferring the same current over the same period of time.
