Question

.Zinc and silver ion react spontaneously by the following reaction skeleton.
_____ Zn(s) _____ Ag^+ (aq) ? _____ Zn^+2 (aq) + _____Ag(s)

1. Balance equation by writing the correct coefficients in the spaces above.
2. Give the voltaic cell shorthand description for this reaction as a voltaic cell. Write anode and cathode under the correct portions of the shorthand description.
3. Show the two half reactions and identify the correct reaction as oxidant or reduction.
4. Calculate the E

Explanation / Answer

Zn(s) + 2 Ag+ (aq) =======> Zn2+ (aq) + 2 Ag(s) Zn(s)/Zn2+(aq)//Ag+(aq)/Ag(s)=====> Cell notation half reaction: Oxidation: Zn(s) =====> Zn2+(aq) + 2 e Reduction: Ag+(aq) + e ====> Ag(s) E
