[单选题]
Consider the following wpme.b:.h 9e frl56)abh,x1t2 swu ykweactions:
$Fe(s) + Cu^{2+}(aq) \rightarrow Fe^{2+}(aq) + Cu(s)$
$Fe(s) + 2Ag^+(aq) \rightarrow Fe^{2+}(aq) + 2Ag(s)$
$Zn(s) + Fe^{2+}(aq) \rightarrow Zn^{2+}(aq) + Fe(s)$
$Cu(s) + 2Ag^+(aq) \rightarrow Cu^{2+}(aq) + 2Ag(s)$
A. Strongest reducing agent is Zn(s) Strongest oxidizing agent is Ag(s)
B. Strongest reducing agent is Zn(s) Strongest oxidizing agent is $Ag^+(aq)$
C. Strongest reducing agent is Ag(s) Strongest oxidizing agent is $Zn^{2+}(aq)$
D. Strongest reducing agent is $Ag^+(aq)$ Strongest oxidizing agent is Zn(s)
参考答案: B
本题详细解析:
Most reactive metal is the strongest reducing agent. Feu6.1di :ckocl displaces Cu and Ag. Zn displaces Fe. Therefore, Zn is the most reactive.
Cations gain electrons ani6:. ukd 1lccod get reduced (oxidizing agent).
