(1). If you make up a solution of 150 mL of 0.1 M TRIS-HCI, what will be the pH?

(2). If you add 3 mL of 1M KOH to the solution in question 2, what will be the pH?

(3). If you make up a solution of 100 mL of 0.15 TRIS-Base, what will be the pH?

*Do the following formulas help to figure out the pH for questions 1 and 2?

pH = (pka - log[HA])/2 - (weak acid formula) & pH = (pka + 14 + log[base])/2 - (weak base formula)

NOTE: I don't accept sloppy writing, express your solutions clearly and with appropriate steps for the client.
