Heat of Neutralisation. I am going to investigate the heat of neutralisation between acids and alkalis. Prediction I predict that no matter what strong acid and alkali react together you will always get the same heat of neutralisation because the same reaction is always taking place. E.g. 1. HCl and NaOH 2. HNO3 and NaOH 3. NO3 and KOH 1. H++Cl¯+Na+ + OH¯ Na++Cl¯ + H2O H+ + OH¯ H2O 2. H+ + NO3¯+ Na++OH¯ Na+ + NO3¯+ H2O H+ + OH¯ H2O 3. H+ + NO3¯ + K+ + OH¯ K+ + NO3¯ + H2O H++ OH¯ H2O I am also going to react 2 weak acids (ethanoic acid and propanoic acid) with a strong alkali (sodium hydroxide.) I predict that the energy change i.e. the heat of neutralisation will not be same as before because with weak acids and alkalis some energy is required to fully ionise them. Heat of neutralisation is the heat change when an acid and an alkali...
