Chapter 15, Problem 15.43P

Interpretation Introduction

Interpretation:

The concentration of $\left[{\text{CO}}_{\text{2}}\right]$ has to be calculated.

Concept Introduction:

Standard additions to one solution:

The graph can be drawn using the equation

$\text{plot}\underset{\text{Function}\text{to}\text{plot}\text{on}\text{y-axis}}{\underbrace{{\text{I}}_{\text{S+X}}\left(\frac{\text{V}}{{\text{V}}_{\text{0}}}\right)}}\text{versus }{\text{I}}_{\text{X}}\text{+}\frac{{\text{I}}_{\text{X}}}{{\left[\text{X}\right]}_{\text{i}}}\underset{\text{function}\text{to}\text{plot}\text{on}\text{x-axis}}{\underbrace{{\left[\text{S}\right]}_{\text{i}}\left(\frac{{\text{V}}_{\text{S}}}{{\text{V}}_{\text{0}}}\right)}}$

Where X-intercept is ${\left[\text{X}\right]}_{\text{i}}$

Electric potential:

The compound electrode which obeys the equation,

$\text{E=constant-}\left[\frac{\text{βRT}\left(\text{ln}\text{10}\right)}{\text{2F}}\right]\text{log}\left[{\text{CO}}_{\text{2}}\right]$
