Chapter 19, Problem 61E
Interpretation Introduction
Interpretation:
Reason for the presence of inexpensive and replaceable zinc plugs in the water is to be stated with explanation.
Concept introduction:
An electrolytic cell is a setup in which reduction and oxidation occurs simultaneously. Oxidation is the loss of .electrons and reduction is the gain of electrons. Reduction and oxidation of any species depends upon the value of standard reduction potential.

- 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.
