at .2M and 10 mL pH= 2.78
at .02M and 1mL pH=3.32
a) Determine the [H3O+]eq from the pH values for each solution.
b) Construct ICE tables and use the initial molarity of [HC2H3O2] for each diluted solution, the equilibrium concentration for [H3O+]eq and the equation below to determine [C2H3O2–]eq and [HC2H3O2]eq.
HC2H3O2(aq) + H2O (l)--> H3O+(aq) + C2H3O2–(aq)
c. Write the Ka expression for the acid dissociation reaction and substitute the calculated equilibrium concentrations in to determine the Ka constant value.
d) Look up the accepted value of Ka for acetic acid in your textbook or other reference text. Calculate the % errror between this accepted value and your calculation.
