Titrations are used to find out concentration.

  • Titrations find out how much acid is needed to neutralise an alkali and vice versa.
  • Use a pipette to measure out a set volume of the alkali. Add a ffew drops of an indicator.
  • Fill a burette with a standard solution of acid.
  • Use the burette to add the acid to the alkali slowly. Swirl the flask regularly. Drop the acid slowly when you think that the alkali is almost neutralised.
  • The indicator will change colour when the alkali is fully neutralised.
  • Record the volume of acid used to neutralise the alkali.
  • Repeat the process a few times, making sure the results are similar. Then take a mean…
