Question

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. Cu(s) Cu2+(aq) Ag+(aq) Ag(s)
B. Cu2+(aq) Cu(s) Ag(s) Ag+(aq)
C. Ag+(aq) Cu2+(aq) Cu(s) Ag(s)
D. 2Ag+(aq) Cu2+(aq) 2Ag(s) Cu(s)
E. Cu(s) Cu2+(aq) 2Ag+(aq) 2Ag(s)

What reaction is occurring at the anode?


A. Ag+ + e– Ag
B. Cu2+ + 2e– Cu
C. Cu Cu2+ + 2e–
D. Ag Ag+ + e–

Answer 1

Where is the arrow. I can't tell between reactants and products.

Answer 2

Two notes here:
1. For question #2, note that oxidiation occurs at the anode. Oxidation, you will recall, is the loss of electrons.

2. For #1, you need to show the separtion of phases as phase 1|phase two followed by || to show the salt bridge then Phase 2|phase 1.

Answer 3

I still don't understand are the reactants on one side of the || and on the other side is products?

for the second one there are 2 answers that could possibly work here
