Video Discription |
Object: To determine the specific rotation of Glucose water solution with the help of polarimeter.
In this video, I, Rohit Gupta have elaborately explained in hindi how to get specific rotation of cane sugar using polarimeter.
A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance and specific rotation is a property of a chiral chemical compound, it is defined as the change in orientation of monochromatic plane-polarized light, per unit distance–concentration product, as the light passes through a sample of a compound in solution. Compounds which rotate the plane of polarization of a beam of plane polarized light clockwise are said to be dextrorotary, and correspond with positive specific rotation values, while compounds which rotate the plane of polarization of plane polarized light counterclockwise are said to be levorotary, and correspond with negative values. If a compound is able to rotate the plane of polarization of plane-polarized light, it is said to be “optically active”.
