  Pipette

  Pipette filler

  Conical flask

  Phenolphthalein

  White tile

  Acid

  Alkali
• What goes in burette?


  The acid
• What goes in the conical flask? 


  The alkali
• Why use a white tile? 


  To make colour change more noticeable
• What is the colour change?

  From pink to colourless when the solution becomes neutral
• Why is a burette used? 


  It measures variable values
• Pipette 


  Measures a fixed value
• What results must you collect? 


  Concordant ones(within 0.1 of each other)
• What do you do with concordant results?

  Calculate a mean
• How do you carry out an accurate titration? 


  By adding the acid DROP-WISE into the conical flask
• A rough titration

  Gives you a rough value for the next ones
