The mass of three different metal electrodes, each from a different galvanic cel

Question

The 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).

Explanation / Answer

the active electrodes are having the mass is foundto be changed as with chemical reaction continous in electrolytic

solution. and also the no change in inert electodes..

now active electrodes is found to be lose in the mass in the reduction reaction and called as anode

sameway the gain in mass is called as cathode.

the electrodes A and C are having change in the mass so these are called active electrodes..

and also A is the cathode electrode..

and C is the anode electrode..

B having no change in mass so it is a Inert electrode..
