I/GCSE Chemistry- Titrations

Practicals

August 21, 2021

This I/GCSE Chemistry blog post will look intoa crucial experimentation called titrations, let's go!

Experiments to Carry Out Acid-Alkali Titrations 

  • Have a known volume of acid in a beaker with methyl orange, the solution will be red as it is very acidic.
  1. Using a pipette, pour the alkali (25cm^2) through a funnel into a burette with alkali in it. 
  2. Open the tap very slightly, so that it drips very slowly into the acid.
  3. With each drop stir the contents of the beaker.
  4. The more alkali that is added the more neutral and closer to orange it gets.
  5. When the solution is neutral the it will be completely orange, at this point close the tap on the burette.
  6. The level in the burette will have dropped, showing the volume of alkali used.
  7. This shows you how much alkali you need to use to neutralise the acid.

That is all for Titrations!
