Chromatographic is the technique to separate various pigments in a leaf extract.

It's a well-known fact that 'those sciences are vain and full of errors which are not born from experimentation, the mother of all certainties.' Keeping this in mind, we at Presidium conducted practical classes for class 12th students to strengthen their grasp over practicals. Various practical work undertaken by students include:

1)Learning Chromatographic techniques to separate various pigments in a leaf extract.

2)Developing crystals of potash alum which we use in our day today life.

3)Learning the concept of neutralization reaction and redox reactions by using titration techniques, many of which are biologically essential for living beings' survival.

4)Test for the functional group like aldehyde, ketones, alcohols, etc., along with nutrients like carbohydrates, proteins, fats, etc.

Through the activities performed over the past few weeks, our students enjoyed going through the cognitive process of science naturally and enhanced their practical knowledge.
