Calculate the pH of a solution formed by mixing 500.0 mL of 0.15 M HCHO2 with 200.0 mL of 0.20 M LiCHO2. The Ka for HCHO2 is 1.8 × 10-4.

Calculate the pH of a solution that contains 7.8 × 10-6 M OH⁻ at 25°C.

A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 0.0500 moles of solid NaOH. Assume no volume change upon the addition of base. The Ka for HF is 3.5 × 10-4.
