Chapter 16, Problem 16.96SP

Acrylic acid ${\text{(HC}}_{\text{3}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\text{)}$ is used in the manufacture of paints and plastics. The ${\text{pK}}_{\text{a}}$ of acrylic acid is 4.25.

1. Calculate the pH and the concentrations of all species ${\text{(H}}_{\text{3}}{\text{O}}^{\text{+}},{\text{C}}_3{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}{}^{\text{-}}{\text{, HC}}_{\text{3}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}{\text{, and OH}}^{\text{-}}\text{)}$in 0.150 M acrylic acid.
2. Calculate the percent dissociation in 0.0500 M acrylic acid.
