Images with description(sorry but not so clear)-3B version 1

These are the 8 teabags with tea leaves.

This is the calcium carbonate powder
This is the mixture that we get after stirring the calcium carbonate powder and the tea leaves.
This is the 'Buchner filtration'

This apparatus was used to give pressure in the flask.
After that we had to put our solution into the cold water basin to cool it.
There are two layers in the separating funnel.This is due to difference in density.
The magnesium sulphate powder clumped in the presence of water.

It's very unclear as the filter paper and the crystals from magnesium sulphate powder are white in colour...
Green caffeine solid
