Concept explainers
Interpretation: A galvanic cell and its working needs to be explained.
Concept introduction: A device which the free energy of a physical and chemical process is converted into electrical energy is known as galvanic cell. Such cell consists of two electrodes immersed in one or more suitable electrolytes.
Explanation of Solution
The structure of galvanic cell is as follows:
In this cell two electrons are immersed in the solution of two compartments. Two solutions are connected through a wire. At last two solutions are connected salt bridge. After the connection is made, current starts following as indicated by the ammeter. No current flows when the metal rods are disconnected or the salt bridge is taken out due to the reaction ceases.

Ag++eAgE=0.80VNi2++2eNiE=0.25Varrow_forwardThe mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).arrow_forwardElectrochemical Cells II Consider this cell running under standard conditions: Ni(s)Ni2(aq)Cu+(aq)Cu(s) a Is this cell a voltaic or an electrolytic cell?
