Introduction.
The following is an experiment into temperature change in an exothermic reaction taking place between Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) and also how the concentration of the acid will vary these results. The characteristics of the reaction feature a neutralisation, an energy change (shown as a temperature change) that is usually exothermic (gives out heat).
The reaction of neutralisation is exothermic because of the bonds being broken and made in the reaction. When bonds are broken, energy in those bonds are taken in, and in this case, are noted as a temper…
