Question

A voltaic cell is constructed with an Ag/Ag half-cell and a Pb/Pb2 half-cell. The silver electrode is positive. Write the balanced half-reactions and the overall reaction. Include the phases of each reactant and product.

Answer 1

Answer:

Following are the chemical equation to the given question:

Explanation:

The Electrode is a silver film that is covered with such a thin coating of silver chloride, either by dipping its wire directly into silver-molten chloride, plating the wire using hydrogen peroxide, or oxidation silver in a chloride. In the given silver electrode, this anode acts as a cathode and thus reduces.

Half of the response reduction: $Ag^+(aq)+e^-\rightarrow Ag(s)$

Half-effect oxidation:  $Pb(s)\rightarrow Pb^{2+}(aq)+2e^-$

Complete reaction:  $Pb(s)+2Ag^+(aq) \rightarrow Pb^{2+}(aq)+2Ag(s)$
