Question

Estimate the pH of 1.5 x 10^-4 M CH₃COOH (aq), being careful to treat this solution as dilute, and not open to the approximations used as given below.

Estimate the pH and the fraction of CH,COOH molecules
deprotonated in 0.15 м СH,СООНaq).

Expert Solution

Step 1

“Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved, then please specify the question number or post only that question.”

Given,

The concentration of CH₃COOH = 1.5 x 10^-4 M

K_avalue of CH₃COOH = 1.8 x 10^-5

Here, K_a = acid ionization constant

pH = -log [H⁺]
