Titration

• 1

  Add volume of alkali to a flask using a pippette
• 2

  Add litmus dye indicator
• 3

  Fill burette with acid
• 4

  Add acid to alkali with swirling until litmus indicator changes colour
• 5

  Record volume of acid added
• 6

  Use white tile to see the colour change
• How to obtain results from titration

  repeat titration and calculate average volume of acid using concordant results
• Why use burette and pipette?

  Pipette measures fixed volume accurately

  Burette measures variable volume accurately
• 7

  Calculate mean titre
