titration is an experiment that you can use to find the concentration of a solution

1. use a pipette to measure out volume of alkali

2. put alkali in a flask with a few drops of indicator

3. using a funnel fill the burette with acid of known concentration

4. run a small amount through the tap then turn it off and place the flask containing the alkali under the burette

5. take a reading of volume of acid in burette by reading off value where bottom of meniscus touches

6. first titration should be rough titration;helps final results be more accurate by giving you an aproximate idea of how much acid is needed to neutralise the alkali. add the acid to the alkali bit at a time and give the flask regular swirls

7. indicator changes colour when alkali has been neutralised. this the end point of the reaction

8. record the volume…
