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.
- Using a pipette, pour the alkali (25cm^2) through a funnel into a burette with alkali in it.
- Open the tap very slightly, so that it drips very slowly into the acid.
- With each drop stir the contents of the beaker.
- The more alkali that is added the more neutral and closer to orange it gets.
- When the solution is neutral the it will be completely orange, at this point close the tap on the burette.
- The level in the burette will have dropped, showing the volume of alkali used.
- This shows you how much alkali you need to use to neutralise the acid.
That is all for Titrations!
