DIRECT METHOD EXAMPLE: A buffer was created by mixing 10 mL of a0.10 M hydrofluoric acid solution with 25 mL of a 0.20 M sodiumfluoride solution. What is this solution’s pH? Do you expect it tobe a ‘good’ buffer with a high buffer capacity or a ‘poor’ bufferwith low capacity? The Ka of hydrofluoric acid is: 7.2 x 10-4. Showwork, thank you.
