Practical on Enthalpy changes between acids and bases Introduction All life on earth depends on the transfers of energy in chemical reactions. So that measurements can be made when energy is transferred during chemical reactions, that have to be carried out under controlled conditions. A special name is given to process where energy is transferred and exchanged with the surroundings, when taking place under constants pressure. The special name given to this type of process is Enthalpy. When chemical reactions take place they release energy to the surroundings. There are also special names given to these kind of energy transfers. They are called exothermic and endothermic reactions. Out of these two types exothermic reactions are most easily detected. This is because in exothermic reactions energy is realised to the surroundings and is detected by temperature rise. But some chemical reactions only occur when energy is put into them from an external source....
