Presidium celebrated National Science Day to mark the discovery of the Raman effect by Indian physicist C.V. Raman. He was awarded the Nobel Prize in Physics in 1930 for his discovery. Students enjoyed Science Day by performing experiments in both Chemistry and Physics. They performed Redox titration in Chemistry and found the molarity and strength of potassium permanganate by titrating it against M/20 Oxalic acid. After the experiment, students understood that they can accurately determine the concentration of an unknown analyzer by measuring it against a standardized titrant. While in Physics they found the focal length of the convex lens and learned to find the radius of the curvature and aperture of the lens and observed the position of image formation.
