should calculate all of the following pH values to two decimal places. 1. Calculate the pH of this solution. 2. Calculate the pH after 0.10mol of HCl has been added to the original solution. Assume no volume change on addition of HCl. 3. Calculate the pH after 0.20mol of NaOH has been added to the original buffer solution. Assume no volume change on addition of NaOH. 1. Tries 0/45 2.
