100 mL of 2.00 M of a solution of hydrochloric acid is added to this buffer. The concentration of the propanoic acid in the solution after the addition of the acid is (Express your answer with two decimal places) The concentration of the propanoate in the solution after the addtion of the acid in (Express your answer with two decimal places) The final pH of the buffer after the addition of the addis (Express your answer to the correct number of slogs.) The change in the pH of the buffer is therefore (Express your answer to the correct number of sig. figuAn algebraic sign must be included, with NO upaca between the sign and the number, og +31)
