Experimental 4: Heat of Neutralization
A. Heat Capacity of Calorimeter
Assuming: heat capacity of calorimeter is zero !!!
B. Heat of Neutralization of HCl+ NaOH
1.0 M NaOH, 50 mL 1.0 M HCl, 50 mL
Temperature before mixing 22oC 22oC
Average (Ti) 22oC
Temperature after reaction (Tf) 32 oC
Calculate
Heat of Neutralization
C. Heat of Neutralization of CH3COOH+NaOH
1.0 M NaOH, 50 mL 1.0 M CH3COOH, 50 mL
Temperature before mixing 22 oC 21.5 oC
Average (Ti) 22 oC
Temperature after reaction (Tf) 27 oC
Calculate
Heat of Neutralization
D. Compare part B and C, discuss the results
