1.) What is the correct net cell reaction for the electrochemical cell diagramed below?

Question

Ni(s) ∣ Ni2+(aq) || Ag+(aq) ∣ Ag(s)

a.) Ag+(aq) + Ni(s) ---> Ag(s) + Ni2+(aq)
b.) Ag(s) + Ni2+(aq) ---> Ag+(aq) + Ni(s)
c.) 2Ag+(aq) + Ni(s) ---> 2 Ag(s) + Ni2+(aq)
d.) Ag(s) + 2 Ni2+(aq) ---> Ag+(aq) + 2 Ni(s)
e.) Ag+(aq) + 2 Ni(s) ---> Ag(s) + 2 Ni2+(aq)

Answer 1

Look up the reductions potentials and see which half cell reacts.
