This Channel initiated by Dr. D. R. Vij (former Professor of Physics, Kurukshetra University, India) primarily aims at taking free education to the doorsteps of learners who for various economic and social factors can not avail benefits of regular coaching.
In view of the congested classrooms coupled with hefty tuition fee, social taboos and hazards of travelling (for girls in particular) this mode of extending education had become a necessity.
This self-learning approach is a definite step towards democratisation of education i.e. taking education even to individuals who staying in remote and far off areas were being deprived of education for no fault of theirs.

Extraction of Sodium by Down's Process, i.e.Extraction by Electrolysis of Molten Sodium Chloride
Difficulties Associated with Extraction and Removal
This video is about extraction of Alkali Metals like Lithium and Sodium. The extraction of these metals is difficult due to high electropositivity, high reducing behaviour and high melting point of their salts. Hence extracted by electrolysis in presence of some impurities. Sodium is extracted by Down's process.
