Experiment 3 : Heat of Reaction Purpose: To measure the heat evolved or absorbed during a chemical reaction. List of Materials used: - (1) Celsius thermometer - (1) 250 mL measuring cup - (1) set of metric measuring spoons - (1) measuring cup calibrated in cubic centimetres - (2) 250 mL polystyrene coffee cups - (4) 500 mL plastic bottles - (1) marking pen - 25g of crystal Drano - 100 mL of muriatic acid Summary of Method (Reaction 1): 1) Measure out 200 mL of labelled water into a large Styrofoam cup. Take a careful reading of the temperature and record as “initial temp” on the table of observations. 2) Measure carefully one level tablespoon of NaOH ( 1 tsp = 5.5g). Pour this into the 200 mL of water and stir to dissolve the solid. Record the highest temperature reached. 3) Repeat to obtain consistent results.

4) Rinse out the reaction vessel thoroughly. Be sure to use the method of disposal recommended by your local authorities. Summary of Method (Reaction 2): 1) Pour 100 mL of 1.0 mol/L HCl into a clean reaction vessel; into another cup place 100 mL of 1.0 mol/L NaOH. Note the temperature of each solution, and record the average of the two
