43. Consider the Henderson-Hasselbalch equation below and briefly answer: \[ \mathrm{pH}=\mathrm{pK}_{\mathrm{a}}+\log _{10} \frac{\left[A^{-}\right]}{[H A]} \] A. What is the conjugate base? A- B. What is the conjugate acid? HA H C. From the Henderson-Hasselbalch equation, define pKa of a conjugate acid/conjugate base pair base. On a titration curve of a monoprotic weak acid with a strong base \( (\mathrm{OH}) \), how can we find the pKa? E. What is the concentration of a conjugate acid and the concentration of its conjugate base at \( \mathrm{pH}=\mathrm{pKa} \) for the conjugate acid/conjugate base pair?
