Thermometric Titration
Aim
To follow the titration and to find the endpoint by measuring the temperature changes take place during the titration. The importance of temperature in the experiment implies there is a connection with heat therefore the experiment is exothermic. Thus the products are at a lower energy level than the reactants so the energy has been given
The acid and alkali we will use is sodium hydroxide and Hydrochloric acid.
Background
If an acid solution is added to an alkaline solution they will react and neutralize each other, forming a salt. The general Formula for this reaction is
Acid + Base Salt + Water
However, the resulting solution will be neutral only if acid and alkali are present in exactly the right quantities. If there is more acid than alkali, the all though all the alkali will be neutralized the solution will remain acid. On the other hand if there is more alkali than acid the solution will remain alkali. The precise volumes of acid and alkali solutions will neutralize each other out exactly.
