Chapter 21, Problem 15E

Interpretation Introduction

Interpretation:

Whether the following process obeys the principal of conservation of charge or not should be determined. Explain.

In sea water, the starting material is ${\text{Mg}}^{2+}$ and the final product is Mg metal in the Dow process.

Concept introduction:

According to the principal of conservation of charges, the total charge of a given isolated system will never change. This means that the net electric charge which is equal to the subtraction of quantity of positive charge and the quantity of negative charge in this universe always remains conserved.
