Chapter 17, Problem 102QRT

Interpretation Introduction

Interpretation:

The potential difference across a nerve cell required to maintain the concentration of ${\text{K}}^{+}$ inside the nerve cell $45$ times greater than that of ${\text{K}}^{+}$ outside the nerve cell has to be calculated.

Concept Introduction:

The cell potential of the cell is defined as a potential difference between two electrodes.  Inside a cell, redox reaction takes place which consists of reduction half-reaction and oxidation half-reaction.  The Nernst equation is used to calculate the cell potential.
