🤓 Based on our data, we think this question is relevant for Professor Shear's class at TEXAS.

FREE Expert Solution

Since the solutions are buffers, we can use the Henderson-Hasselbalch equation to calculate the pH

pH=pKa+logconjugate baseweak acid



• CH3COOH→ weak acid. It will give its conjugate base when it loses H+

CH3COOH(aq) + H2O(l) → CH3COO-(aq) + H3O+(aq)

• CH3COONa is the salt of the conjugate base of acetic acid. It will completely dissociate in a solution

CH3COONa → CH3COO- + Na+

  • Na+ is neutral and has no effect in pH
