For the following balanced equation: 2 Ag+ (aq) + Cu(s) <<->> Cu2+ (aq) + 2 Ag(s)
Which letter corresponds to the correct cell notation at standard state conditions?
A. 2Ag+(aq) | Cu2+(aq) || 2Ag(s) | Cu(s)
B. Cu(s)| Cu2+(aq) || Ag+(aq) | Ag(s)
C. Ag+(aq) | Cu2+(aq) || Cu(s) | Ag(s)
D. Cu2+(aq)| Cu(s) || Ag(s) | Ag+(aq)
E. Cu(s) | Cu2+(aq)|| 2Ag+(aq) | 2Ag(s)
What reaction is occurring at the anode?
A. Cu -> Cu2+ + 2e–
B. Cu2+ + 2e– -> Cu
C. Ag+ + e– -> Ag
D. Ag -> Ag+ + e–
Is it B , A?
