Question: Malic acid (C 4 H 6 O 5 ) is one of the alpha hydroxy acids which is naturally found in apples. The reaction of

Malic acid (C₄H₆O₅) is one of the alpha hydroxy acids which is naturally found in apples. The reaction of hydrochloric acid with sodium maleate to form malic acid and sodium chloride is according to the following equation:

HCl + C₄H₅O₅Na ------> C₄H₆O₅ + NaCl

You have been asked to prepare a maleate buffer (K_a = 3.908 x 10^-4 ) using sodium maleate (M.W.= 178.05 g/mol) and 0.200 M HCl. How many millilitres of HCl should you add to 250.00 mL of 0.300 M sodium maleate to produce a buffer solution with a pH of 3.37?
