You want to set up a series of voltaic cells with specific cell potentials. The Ag + (aq, 1.0 M) | Ag(s) half-cell is one of the compartments. Identify several half-cells that you could use so that the cell potential will be close to (a) 1.7 V and (b) 0.50 V. Consider cells in which the silver cell ran he either the cathode or the anode.

You want to set up a series of voltaic cells with specific cell potentials. The Ag+(aq, 1.0 M) | Ag(s) half-cell is one of the compartments. Identify several half-cells that you could use so that the cell potential will be close to (a) 1.7 V and (b) 0.50 V. Consider cells in which the silver cell ran he either the cathode or the anode.

(a)

Interpretation Introduction

Interpretation:

The half-cells which can be used to produce a cell potential of 1.7V has to be identified and the cells in which the silver cellcan be either cathode or anode has to be determined.

Concept introduction:

Voltaic cell or Galvanic cell:

The device to produce electricity by using chemical reactions. In these divces are redox chemical reactions are occured.

A voltaic cell converts chemical energy into electrical energy.

It consists of two half cells. Each half cell consists of a metal and a solution of a salt of metal. Two half cells are connected by salt bridge.

The chemical reaction in the half cell is an oxidation reduction (redox)reactions.

For example:

Cell diagram of voltaic or galvanic cell is as follows.

                 Salt bridge                        Cu(s)|Cu2+(aq)  ||  Ag+(aq)|Ag(s)____________     ___________                                       Half cell             Half cell

Explanation of Solution

For 1.7 V

Ag+(aq) Ag(s) at the anode.

Let’s write the half cell reactions.

At anode:Oxidation: H2+2OH 2H2O + 2e-At cathode:Reduction: 2Ag+(aq) + 2e- Ag(s)

The net reaction is as follows

Interpretation Introduction

Interpretation:

The half-cells which can be used to produce a cell potential of 0.50V has to be identified and the cells in which the silver cellcan be either cathode or anode has to be determined.
