determine the pH of a solution made by mixing 8 ml of 1.10M acetic acid and 2ml 0.9 M sodium acetate solution. pKa for acetic acid CH3COOH is 4.745.

Question

Can someone please explain

Answer 1

Acetic acid is a weak acid; sodium acetate is a salt of a weak acid. The combination makes a buffered solution. You calculate pH from the Henderson-Hasselbalch equation.
