Concept explainers
Interpretation: The line in the given Figure that best represents the dependence of the degree of ionization of acetic acid on its concentration in aqueous solution is to be stated.
Concept introduction: Degree of ionization is defined as the ratio of the number of molecules ionized in an aqueous medium to the total number of molecules dissolve in the aqueous medium. The measure of concentration of ions in a solution gives the ionic strength of the solution.
To determine: The line in the given Figure that best represents the dependence of the degree of ionization of acetic acid on its concentration in aqueous solution.

Answer to Problem 15.1VP
Solution
The red line best represents the nature of acetic acid.
Explanation of Solution
Explanation
The given figure is,
Figure 1
The given acid is acetic acid which is a weak acid. The degree of ionization is inversely proportional to the square root of molar concentration according to Ostwald’s dilution law.
In the given graph, the green line shows that there is no effect of concentration on the degree of ionization. Therefore, it is not applicable for an acetic acid. The yellow line shows a tremendous change in the degree of ionization by the change in concentration, this does not happen for a weak acid like an acetic acid.
Therefore, it does not represent acetic acid. The blue line represents the change in degree of ionization by the change in concentration in a continuous manner. In a weak acid, the change in degree of ionization is not continuous. Thus, it also does not represent acetic acid. The red line shows that the degree of ionization increases with the decrease in concentration of an acid.
Thus, the red curve represents the degree of ionization for the acetic acid.
Hence, in all the lines shown in Figure 1, red line best represents the nature of acetic acid.
Conclusion
The red line best represents the dependence of the degree of ionization of acetic acid on its concentration in aqueous solution.
