what is the pH of a solution prepared by mixing 20.0mL of 0.5M NaOH and 35.0mL of 0.5 benzoic acid solution? (benzoic acid is monoprotic with a Ka of 6.5x10^-5.) please provide the work along with the answer and try to make the work as simple as possible!
When a student mixes 50 of M HCI and 50 mL of 1.0 M NaoH in a coffee-cup calorimeter, the temperature of the resultant solution increases from 21.0 degree C to 27.5 degree C. Calculate the enthal change (delta H) for the reaction in kJ/mol HCl. (Assuming that the calorimeter loses only a negligible quantity heat, that the total volume of the solution is 100 ml, that its density is 1.0 g/mL, and that its specific heat is 4.18 J/g...
