3) What is the pH of a buffer solution made by adding 0.15 mole of lactic acid HC,H,O, and 0.12 mole sodium lactate to enough water to make 1.0 L of solution? What is the concentration of the hydroxide ion in the solution? K, lactic acid = 1.4 x 10 -4 4) A titration of 25.00 mL sample of a hydrochloric acid solution of unknown molarity reaches the equivalence point when 38.28 ml of a 0.4270 M NAOH solution has been added. What is the molarity of the HCl solution?
