Titrations

Cards (3)

  • 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
