Write the reaction for the ionization of acetic acid in water, and use the known Ka value and an ICE table to calculate the concentration of hydronium ion at equilibrium for a solution that has an initial acetic acid concentration of [HC2H3021-1.50M Assume the initial concentration of hydronium and acetate in solution is negligible, and Ka-1.8E-05. [H30*]: Report your answer in scientific notation in the form "X.XE-X" Question 4 2 pts What is the pH of the solution in Question 3?
