Describe in detail the construction and working of Laurent’s half-shade polarimeter. Explain how you would use it to determine the specific rotation of a sugar solution. Step-by-step solutionArticles for tag: formula for specific rotation, how to calculate specific rotation, laurent's half shade polarimeter, polarimeter experiment, specific optical rotation interview questions, specific rotation, specific rotation and optical rotation, specific rotation calculator, specific rotation definition, specific rotation formula, specific rotation glucose, specific rotation in polarimeter .
5. While measuring the angles of rotation, the two halves of the half-shade plate should be equally bright. Failure to judge the equality of brightness will introduce errors. To minimize those errors, four readings should be taken for each concentration. Questions 1. How does polarized light differ from the ordinary light? 2. What is optic axis?This document contains 24 questions and answers about the polarimeter experiment. Key points covered include: 1) Light waves are transverse electromagnetic waves, with the electric field component playing the role of .
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.
Polarimeter, Electric bulb with housing, sugar, balance, graduated cylinder and thermometer. . As shown in fig.1, Source is the Sodium Vapor lamp fitted in housing, P.Nicol, the polarizing Nicol, H, the Half shade device, A Nicol, the analyzing Nicol and Eye piece is the observing eye piece and solution is contained in the tube with glass end.A polarimeter consists of two Nicols termed as polariser and analyser. These can be rotated about a common axis and the substance for which the rotation is to be determined, is placed in a tube in between these two. The half shade plate is placed between the polariser and the solution tube (cf., Fig. 3).
