You are preparing a solution with Boris. Boris placed 60.5 g of K,C,H_O along with 0.320 moles of HCI into a total volume of 750.0 mL of distilled water. You stirred the solution and then measured the pH. What is- the pH of this solution? Later Boris added 16.0 mL 3.9 M of HCI into the previously prepared solution. You stirred the solution and then measured the new pH. What is the new pH? Possibly useful information: Ka, = 6.2 x 105 Kaz = 2.3 x 106 Molar Mass of H2CH&O4 = 118.10g/mol Molar Mass of HCHO 117.09 g/ mol Molar Mass of CaH&O q = 116.08 g/ mol
