Interpretation Introduction

Interpretation:

The anode, cathode, overall reaction and the direction of electron flow in the external wire has to be determined.

  Reduction: Ag+(aq)+e- Ag(s)Oxidation: Ni(s) Ni2+(aq)+2e-

Concept introduction:

Voltaic cell or Galvanic cell:

This device is used to produce electricity by chemical reactions and these reactions are redox reactions.

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
