The angle through which plane polarized light is rotated by the reacting mixture is measured by:
Answer: optical rotation method
Explanation
The angle through which plane-polarized light is rotated by a reacting mixture is measured by the optical rotation method.
Optical rotation, also known as optical activity, is a property exhibited by certain substances
That causes them to rotate the plane of polarized light passing through them
This rotation is quantified by measuring the angle of rotation, typically using a polarimeter
