Apparatus: The apparatus that I will be using in this experiment will be:

  • A Burette
  • A Clamp and Stand
  • 2x 50ml Beakers
  • A Conical Flask
  • A Measuring Cylinder
  • A Thermometer
  • Universal Indicator
  • 25ml Hydrochloric Acid
  • 25ml Sodium Hydroxide

Method/Plan of the experiment:

First of all, I will set up the apparatus as the diagram shows:

Then, I will measure out the acid and alkali using the measuring cylinder. Once I have done that, I will pour the 25ml of Hydrochloric Acid in to the conical flask. I will also pour the 25ml of Sodium Hydroxide into the burette, and adding 1cm cubed of alkali at a time into the conical flask, I will record the temperature of the solution made by the two substances. By now, I will have also put the Universal Indicator into the conical flask, and I will stop the experiment when the solution is neutral, which should be when the alkali in the burette runs out.

I think that as the two solutions are added together, they will cause the temperature of their solution to rise as the neutralisation takes place. This is because when energy in the form of heat is given out of a reaction it is an exothermic reaction. Exothermic reactions usually need activation energy, the energy to break the bonds in the chemicals and to start the reaction. Once the bonds are broken new stronger bonds are formed. In an exothermic reaction energy in the form of heat is given out to the surrounding when the products are formed. Therefore ...
