Acrylic acid is a monoprotic weak acid with the formula, HC3H3O2, and a Ka value of 4.47x10-5 at 25oC.
1) Calculate the (a) pH and (b) % dissociation of a 1.50M HC3H3O2 solution.
2) Given that the Ka of HC3H3O2 4.47x10-5 at 25oC, find the value of Kb for its conjugate base .
3) Calculate the pH of a solution prepared by mixing 0.800L of 0.500M HC3H3O2 with 0.700L of 0.650M C3H3O2-. Assume the volumes are additive.
