Titrations

• What are titratuons used for?

  finding out concentrations
• What is the method for the experiment for titrations?

  -using a pipette add a set volume of the alkali to a conical flask. Add 2 drops of indicator

  -use a funnel to fill a burette with the acid and record initial volume

  -use the burette to add the acid to the alkali a drop at a time and give the council flask a regular swirl

  -when the indicator has changed colour all the alkali has been neutralised

  -record the final volume in the burette and calculate the volume of acid used
• You should repeat titrations to find the mean volume
