We’re being asked to calculate the pH of a solution that is 1.00 M HF and 0.20 M KF.
A solution that contains a weak acid and its conjugate base is a buffer solution. The pH of a buffer solution can be determined using the Henderson-Hasselbalch equation.
The solution is composed of 1.00 M HF and 0.20 M KF.
• HF is a weak acid
• the anion in KF is the conjugate base
Calculate the pH of a solution that is 1.00 M HF and 0.20 M KF. Ka = 7.24 x 10-4
