Question
**Problem Statement:** Determine the pH change when 0.102 mol KOH is added to 1.00 L of a buffer solution that is 0.400 M in HF and 0.349 M in F⁻. **Calculation:** pH after addition – pH before addition = pH change = [Input Box] **Explanation:** This exercise involves calculating the change in pH of a buffer solution upon the addition of a strong base (KOH). - The buffer solution consists of hydrofluoric acid (HF) and its conjugate base fluoride (F⁻). - The concentrations of HF and F⁻ before the addition are 0.400 M and 0.349 M, respectively. - After adding 0.102 mol of KOH, determine how the equilibrium shifts and calculate the resulting pH. The goal is to understand how well the buffer can maintain its pH when a strong base is introduced.
