Write the reaction equations of a voltaic cell with Ag+ & Sn2+

Question

A voltaic cell is based on the reduction of Ag⁺(aq) to Ag(s) and the oxidation of Sn(s) to Sn²⁺(aq).

A. Half Reaction of Cells Anode

B. Half Reaction of Cells Cathode

C. Write a balanced cell reaction. Include the phases of all species in the chemical equation.

Answer 1

Oxidation takes place at the anode and reduction takes place at the cathode.

A. Half reaction at the anode:

Sn(s) ==> Sn²⁺(aq) + 2e- (oxidation at the anode)

B. Half reaction at the cathode:

Ag⁺(aq) + e- ==> Ag(s) (reduction at the cathode)

C. Balanced cell reaction (multiply reduction reaction by 2 to equalize electrons being transferred)

Sn(s) + 2Ag⁺(aq) ==> Sn²⁺(aq) + 2Ag(s)
