Identify the methods used to monitor a reaction as it occurs in the reaction flask.

Question

Quizplus · Accepted Answer

All three methods, polarimeter, spectrometer, and pressure measurement, can be used to monitor a reaction as it occurs in the reaction flask. The polarimeter measures the rotation of polarized light caused by the chiral molecules present in the reaction mixture, which can show how much of the chiral reactant is left in the mixture. The spectrometer can measure changes in the absorption or emission of light as the reaction proceeds, indicating changes in the concentration of certain species. Pressure measurement can be used to monitor gas-forming reactions and can indicate the progress of the reaction as the pressure changes over time. Therefore, all of the above methods can be used to monitor a reaction as it occurs in the reaction flask.
