A solid acid is dissolved in enough water to make 200 mL of a solution. 40.0 mL of the solution is titrated to a phenolphthalein endpoint with a NaOH solution. The neutralized solution and the remainder of the acid solution are then mixed, and the pH of the resulting solution is found to be 3.35. Find the Ka of the acid. Show your complete solution.
