3. The pH of the given solution of lactic acid and lactate is 4.30. Calculate the pKa
of lactic acid, when the concentration of lactic acid and lactate are 0.020 M and
0.073 M respectively.
What is the pKa of benzoic acid?
What is the molar concentration of sodium benzoate (conjugate base)?
What is the molar concentration of benzoic acid (weak acid)?
A buffer was created using ascorbic acid and sodium ascorbate. What is the pH of the buffered solution if at equilibrium
