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

Following are the chemical equation to the given question:

Step-by-step 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)`
