Chapter 8: Q12P (page 183)

Find the activity coefficient of $H^{+}$ in a solution containing $0.010 M HCI$ plus $0.040 M {KCIO}_{4}$ . What is the pH of the solution?

Short Answer

Expert verified

Thus the activity coefficient of $H^{+}$ is $γ (H^{+}) = 0.86$ and pH of role="math" localid="1654858154412" $H^{+}$ is 2.07

Step by step solution

Step 1:Finding the activity coefficient of solution H+

In this problem, we need to find the activity coefficient of $H^{+}$ in a solution containing $0.010 M HCI$ plus $0.040 M {KCIO}_{4}$ and also we need to find the pH value of the solution.

First, we need to find the activity coefficient of $H^{+}$ by calculating the ionic strength $(μ)$ ,

$μ (HCI) + μ ({KCIO}_{4}) = 0.001 M + 0.04 M = 0.05 M$

From the Table $8 - 1$ we can see that the activity coefficient of localid="1654858360555" $H^{+}$ is

$γ (H^{+}) = 0.86$ when $0.05 M$

Calculating the pH value of the solution H+.

The pH value of the solution can be calculated by,

$pH = - logμ (H^{+}) γ (H^{+}) pH = - \log (0.01 \times 0.86) pH = 2.07$

Thus the activity coefficient of $H^{+}$ is $γ (H^{+})$ and pH of $H^{+}$ is 2.07
