Titration

Cards (6)

  • Step 1: Use a bulb pipette to measure 25 cm^3 of alkali and put it into a conical flask
  • Step 2: Fill burette with acid and fill it past 100 cm^3 and drain to 100 cm^3
  • Step 3: Do a rough titrate (go fast) to give and estimated volume needed
  • Step 4: Do more precise titrates by going to close to the rough titrate and adding acid drop by drop
  • Step 5: Repeat steps 1,2&4 until results are concordant
  • Phenolphthalein is put into the alkali to show neutralisation has occurred
