Acrylic acid \(\left(\mathrm{CH}_{2}=\mathrm{CHCO}_{2} \mathrm{H}ight)\) is a precursor for many important plastics. ( \(K_{\mathrm{a}}\) for acrylic acid is \(5.6 \times 10^{-5}\).) a. Calculate the \(\mathrm{pH}\) of a \(0.10 \mathrm{M}\) solution of acrylic acid.

b. Calculate the percent dissociation of a \(0.10 \mathrm{M}\) solution of acrylic acid.

c. Calculate the \(\left[\mathrm{H}^{+}ight]\)necessary to ensure that the percent dissociation of a \(0.10 \mathrm{M}\) solution of acrylic acid is less than \(0.010 \%\).

d. Calculate the \(\mathrm{pH}\) of a \(0.050 \mathrm{M}\) solution of sodium acrylate \(\left(\mathrm{NaC}_{3} \mathrm{H}_{3} \mathrm{O}_{2}ight)\).
