Lactic acid, received its name be-cause it is present in sour milk as a product of bacterial action. it is also responsible for the soreness in muscles after vigorous exercise. (a) The of lactic acid is 3.85. Compare this with the value for propionic acid and explain the difference. (b) Calculate the lactate ion concentration in a 0.050 M solution of lactic acid. (c) When a solution of sodium lactate, is mixed with an aqueous copper(II) solution, it is possible to obtain a solid salt of copper(II) lactate as a blue-green hydrate, Elemental analysis of the solid tells us that the solid is 22.9% Cu and 26.0% C by mass. What is the value for x in the formula for the hydrate? (d) The acid-dissociation constant for the Based on this value and the acid-dissociation constant of lactic acid, predict whether a solution of copper(II) lactate will be acidic, basic, or neutral. Explain your answer.
