I made this project in XII-

Aim - To detect the presence of caffeine in various tea brands available in market.

Apparatus required -

Test tubes,Flasks and conical flask,Funnel,Bunsen burner,Tripod stand,Wire Gauze,Glass rod,Filter paper.

Chemicals required -

Samples of tea,Calcium Carbonate,Dil. H2SO4,Chloroform (CHCl3) ,Distilled water

Procedure -

1-Take 10g of tea sample.

2-Add 100mL of distilled water in a 400 mL beaker and boil it. Add first sample of tea to it and boil for 10 minutes. Cool and filter the solution.

3-To the filtrate, add 2g of Calcium Carbonate (CaCO3) and boil the content. Tannic acid gets precipitated as Calcium Tannate. Separate the precipitate of calcium tannate by filtration.

4-Add 1mL of Dil. H2SO4 to the filtrate. Lead gets precipitated as PbSO4.

5-Remove the precipitate by filtration and extract the filtrate with Chloroform (CHCl3) 3-4 times.

6-Combine the CHCl3 extract and remove the solvent by heating on a steam bath.

7-The residue left behind is caffeine.

8-Weigh the caffeine left behind.

Hope it helps you.

Or study the setting of cement

Or Extraction of iron from spinach leaves

Or experiment showing equilibrium
