Chapter 15, Problem 15.88SP

Acrylic acid ( ${\text{HC}}_3{\text{H}}_3{\text{O}}_2$) is used in the manufacture of paints and plastics. The $\text{pK}$of acrylic acid is 4.25.(a) Calculate the pH and the concentrations of all species ( ${\text{H}}_3{\text{O}}^{+}$, ${\text{C}}_3{\text{H}}_3{\text{O}}_2{}^{\text{-}}$, ${\text{HC}}_3{\text{H}}_3{\text{O}}_2$, and ${\text{OH}}^{-}$) in 0.150 M acrylicacid.(b) Calculate the percent dissociation in 0.0500 M acrylic acid.
