Investigation into how much heat is produced in a neutralisation reaction. Background Information. All neutralisation reactions give out more heat than is taken in. This type of reaction is called an exothermic reaction. The basic reaction will be H with OH ions. The H will always be the acid and the OH will always be the alkali. When; H+ + OH- H2O + Salt 1mol 1mol 1mol 1mol = 58 000 jmol of energy is given off (data book value) This is regardless of which acid and which alkali are used for the reaction, but the type of salt does depend on the type of acid and alkali used. The equation used to find the ?Hr is ?Hr = m x 4.20 x ?T m = mass of solution in beaker 4.2 = specific heat capacity of water ?T = Heat...
