Heat of Solution 1. Weigh the cleaned and dried calorimeter and record mass below 2. Place about 50ml. of distilled water in calorimeter and weigh and record below 3. Measure the water in the calorimeter (original temp of water) and record below 4. Weigh out approx. 5g of solid assigned (record unknown #) in a metal weighing pan and record mass below (record all digits from balance) 5. Add salt to calorimeter, stir quickly and watch temperature. 6. Record the maximum or minimum temperature reached making sure all solid is dissolved (should be at least 5C. Solid unknown # Mass of empty Calorimeter Mass of Calorimeter plus water Mass of water Mass of solid Original temp of water Final Temp of water Change in temp QH,0 (show calculation) AH reaction (show calculation) 720 2 50.0 5.00 21 14 7 1604.3 'C C Calculate heat of solution per gram of solidishow calculation) Actual AH reaction Is the solution reaction endothermic or exothermic.
