QUESTION 8
Consider the diprotic acd HA with Kat21x 10and K-27 1010 Find the pH of a 0.150 M NapA solution.
QUESTION 9
A monoprotic base B has a pk-643 f 16.0 ml of a0.370 M solution of B is srated with a 0.500 M solution of HCI what is the pH of the solution after 18.00 of titrant has
been added? Answer to three decimal places
