Question

Acrylic acid (HC3H3O2) is used in the manufacture of paints and plastics. The pKa of acrylic acid is 4.25. Calculate the concentration of HC3H3O2 in 0 160M acrylic acid. Express your answer to two significant figures and include the appropriate units. Calculate the concentration of OH- in 0.160M acrylic acid. Express your answer to two significant figures and include the appropriate units. Calculate the percent dissociation in 0.0480M acrylic acid. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

Part D) 0.16 M Part E) X^2 / 0.16-X = 10^-4.25 = 5.62 x 10^-5 ......=> X = 0.003 M ...=> [H+] = 0.003 M .........=> [OH-] = 10^-14 / 0.003 = 3.33 x 10^-12 M Part F) (0.048 x X)^2 / (0.048 (1-X)) = 5.62 x 10^-5 .........=> X = 0.034 ........=> % dissociation = 3.4 %
