Question:
What is the activity coefficient of H{eq}^+ {/eq} in a solution containing 0.020 M HCl and 0.010 M Ca(CIO{eq}_4 {/eq}){eq}_2 {/eq}?
What is the pH of this solution?
Activity Coefficient:
The activity coefficient is a parameter for a chemical which is defined as the degree of deflection in concentration of a solution as compared to an ideal one. We must take into account the activity of the protons to determine the pH. The pH is measured by using a pH meter which measures the activity of the hydrogen ions expressed by the equation below:
{eq}\rm pH = -log\; A_{H^+} \\ pH = -log\;[H^+ ] \times \gamma _{H^+} {/eq}
The activity is calculated by taking the product between the activity coefficient and molar concentration. The value of γ is the activity coefficient that quantifies the deviation from ideal behavior.
