Chemistry Heats of Neutralization

             Chemistry Coursework Heats of Neutralisation
             In our investigation, we are trying to find out how the reaction of neutralization has an effect on the temperature of a solution that is neutralizing. Before we can begin our experiment, we need to finds out which chemicals of the below list we will use for the investigation. We will use every combination in the pre trial to see which are the most reactive.
             Hydrochloric Limewater
             Sulphuric Acid + Alkali Sodium Hydroxide
             Ethanoic Ammonia
             These are the reactions we used in the pre trial and their results-
             Sulphuric Acid 20ml + limewater 180ml- 22c at start, 25c at end -3c change
             " " + Ammonia 38ml- 22c at start, 25c at end, - 3c change
             " " + Sodium hydroxide 20ml- 22c at start, 25c at end, -8c change
             The experiment that we have decided to do is neutralising acid with an alkali and the reaction we have chosen is
             Sulphuric acid + Sodium hydroxide Water + Sodium sulphate
             We have chosen this reaction because we can see from our pre trial results that this is the reaction that should produce the most heat and this is why will use it to get the highest range of temperatures that will make analysing the data easier.
             Thermometer, burette, pipette, pipette filter, measuring cylinder, clamp and stand, data logger, sulphuric acid, sodium hydroxide and universal indicator.
             For safety, we will wear goggles to avoid getting any of the acids or alkalis in our eyes, as they are corrosive and will burn.
