A) \[Zn(s)+2A{{g}^{+}}(aq)\,\to \,Z{{n}^{++}}(aq)+2Ag(s)\]
B) \[Z{{n}^{++}}(aq)+2Ag(s)\,\to \,2A{{g}^{+}}(aq)+Zn(s)\]
C) \[Zn(s)+Ag(s)\,\to \,Z{{n}^{++}}(aq)+A{{g}^{+}}(aq)\]
D) \[Z{{n}^{++}}(aq)+A{{g}^{+}}(aq)\,\to \,Zn(s)+Ag(s)\]
Correct Answer: A
Solution :
\[\overset{o}{\mathop{Z{{n}_{(s)}}}}\,+2Ag_{(aq)}^{+}\to Zn_{(aq)}^{2+}+\overset{o}{\mathop{2A{{g}_{(s)}}}}\,\] In this reaction zinc act as a anode and \[Ag\] act as a cathode.You need to login to perform this action.
