When 100 mL of 1 0 M HCI was mixed with 100 mL of 1 0 M NaOH in an insulated beaker at constant pressure a temperature increase of 5 7 C was measured for the beaker and its contents Expt 1 Because the enthalpy of neutralization of a strong acid with a strong base is a constant 57 0 kJ mol this experiment could be used to measure the calorimeter constant In a second experiment Expt 2 100 mL of 2 0 M acetic acid Ka 2 0 x 105 was mixed with 100 mL of 1 0 M NaOH under identica conditions to Expt 1 where a temperature rise of 5 6 C was measured Consider heat capacity of all solutions as 4 2 J g K and density of all solutions as 1 0 g mL 1 2015 3 Enthalpy of dissociation in kJ mol of acetic acid obtained from the Expt 2 is A 1 0 B 10 0 C 24 5 D 51 4 The pH of the solution after Expt 2 is A 2 8 C 5 0 B 4 7 D 7 0 your A Dr Sup 20 whiny om bo state
