Question

MCQ (Single)Buffer Solutions and Their Action

For the buffer system of acetic acid (CH3COOH) and sodium acetate (CH3COONa), the Henderson-Hasselbalch equation is:

What is the pH of a buffer solution prepared from 0.1 M acetic acid and 0.1 M sodium acetate? (Given pKa of acetic acid = 4.76)

pH Scale for Measuring Acidity and Basicity

Calculate the pH of a buffer solution containing 0.1 M CH3COOH and 0.1 M CH3COONa. (pKa of CH3COOH = 4.76)

For a buffer solution, if the ratio of [A-]/[HA] is 10 and pKa = 4, calculate the pH.

0.2 mole of CH3COOH are half neutralised by adding NaOH solution. If Ka for CH3COOH is 1.3 x 10-8, calculate the pH of the solution.

Calculate the pH of a buffer solution made from 0.2 M acetic acid and 0.2 M sodium acetate, given that the pKa of acetic acid is 4.76.
