WebOne way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution. When … WebTranscribed Image Text: QUESTION 1 A buffer solution contains a weak acid, HA, and its conjugate base,A". The buffer solution has a pH of 5.94, and the weak acid has a K₂ of 5.3x10-6 Determine the relationship between the concentration of the weak acid and the concentration of the conjugate base in this buffer solution.
