Question
Prelab Questions-Enthalpy of Neutralization of Mineral Acids Record the values for questions 1, 3 and S in the space provided on the bottom of page 3 of the experimental instructions 1. Using AH, values from the Appendix in your textbook, calculate aHn for the aqueous reaction of HCI with NaOH 2. Calculate the expected ?? when S0.0 mL of 1.85 M NaOH is added to 50.0 M of 1.80 M HCl. Using ??, values from the Appendix in your textbook, calculate aan for the aqueous reaction of H:SOs with NaOH. 3. 4. Calculate the expected AT when 50.0 ml of 1.85 M NaOH is added to 50.0 M of 1.80 M H,so
Explanation / Answer
1) HCl (aq) + NaOH (aq) ---------> NaCl (aq) + H2O (l)
delta H values(kJ/mol): - 167.159 -470.114 -407.27 -285.83
delta Hrxn = [ (-407.27) + (-285.83)] - [ (- 167.159)+( -470.114)] = [-693.81] - [ -637.273] = - 56.537 kJ
