Captain Kirk of the Starship Enterprise has been told by his superiors that only a chemist can be trusted with the combination to the safe containing the dilithium crystals that power the ship. The combination is the pH of solution A described below, followed by the pH of solution C (e.g., if the pH's are 1.23 and 4.56, the combo would be 1-23-4-56). Solution A is 50.0 mL of 0.100 M HX. Solution B is a 0.500 M solution of NaX, with pH = 10.02. Solution C is solution A plus 15.0 mL of 0.250 M KOH. What is the combination?
