Which row, indicated in the table below, conta,i4 .y9t 0tuc zthn9seins the correct spkh:wokath r s*)8l(, xecies that are produced at each electrode during the electrol8 txolk:rkhh ,( aw*)sysis of molten zinc chloride?
A. Negative electrode (cathode) is Zn(s), Positive electrode (anode) is $Cl_2(g)$
B. Negative electrode (cathode) is $Zn^{2+}(I)$, Positive electrode (anode) is $Cl^-(I)$
C. Negative electrode (cathode) is $Cl^-(I)$, Positive electrode (anode) is $Zn^{2+}(I)$
D. Negative electrode (cathode) is $Cl_2(g)$, Positive electrode (anode) is Zn(s)
参考答案: A
本题详细解析:
$Zn^{2+}(I)$ gains electrons and is reduced to Zn(s) at the cathode. $Cl^-(I)$ loses electrons and is oxidised to $Cl_2(g)$ at the anode.
