CALORIMETRYObjectivesUpon completion of this lab, we will learn to measure the heat of the reaction under constant pressure conditions. Calculate the enthalpy change for a reaction using the enthalpy change of 2 other reactions and Hess’s law of heat summation. ProceduresREACTION 11.Measure exactly 100.0mL of deionized water. Add the water to a Styrofoam cup and record the initial temperature. 2.Measure about 2.000 grams of solid NaOH and record the exact mass. 3.Add the solid NaOH into water and start swirling the cup to dissolve all the pellets4.Record the final temperature. 5.Rinse the Styrofoam cup and the temperature probe with deionized water. REACTION 21.Measure exactly 50.00mL of deionized water. Add the water to Styrofoam cup and record the initial temperature. 2.Measure exactly 50.00mL of 1.0M HCl 3.Measure about 2.000 grams of solid NaOH and record the exact mass4.Add HCl into water5.Add solid NaOH into the mixture in step 46.Record the final temperature. REACTION 31.Measure exactly 50.00mL of 1.0M HCl. Add this into Styrofoam cup and record the initial temperature2.Measure exactly 50.00mL of 1.0M NaOH3.Add the aqueous NaOH into HCl 4.Record the final temperature.
