Chapter 8, Problem 8.22P

Interpretation Introduction

Interpretation:

The observation has to be explained when charge balance does not exist in solution and also could two elephants hold the two beakers apart or not has to be checked.

Concept introduction:

Charge balance:

The overall positive charges in solution equals the overall negative charges in solution.

I.e. Solution should be neutral (electroneutrality)
