Here is your answer ↙️↙️✌️✌️☺️☺️
Step 1: Use 1/2(cz^2) to find u (ionic strength)
For this example it would be u=0.05
Step 2: plug u into the activity coefficient equation (-0.51)z^2(sqrt(u)) / (1+ (a*(sqrt(u))/3-5) where a is the size of H ion (from table 7-1). Be sure to take the anti-log of your answer to get the activity coefficient! log(gamma)= -0.06867 so gamma= 0.86
You can use this activity coefficient and [H+] to find pH...
pH= -(log(0.010M) +log(0.86))
Hope this helps you ☺️☺️⭐✨✨⭐
