Heat of Neutralization for an acid-base reaction Contents: - Abstract - Introduction - Results and Discussions - Conclusion - References Abstract: In the experimental procedure we will measure the heat of neutralization when an acid and base react to form 1 mole of water. This quantity of heat is measured experimentally by allowing the reaction to take place in a thermally insulated Styrofoam cup calorimeter. The heat liberated in the neutralization reaction will

P9/M4- Determination of Abstract: The aim of this experiment was to find out which alcohol burner was the most efficient when heating up water. The different alcohol burners were placed under cans full of 100cm3 of water one after the other. There was a thermometer placed in the can‚ which measured the temperature change during the experiment. It was noticeable that the most efficient alcohol burner was Octan-1-ol as its average was 16.4KJ whilst most other burners were less than 10KJ.
