Question

Question 5 Calculate the ratio of oxalic acid and oxalate required in a buffer system of pH 3.85. The pKa of oxalic acid is 4.20. Question 6 What are the concentrations of acetic acid and sodium acetate in a 0.40 M acetate buffer, pH 5.35? The Ka of acetic acid is 1.7 x 10-5. Molarity of the buffer is a sum of concentrations of the acid and its conjugate base.
