Expert Solution & Answer

Explanation of Solution

Single beam spectrophotometer has a separate mount for blank cuvette before the test run.

In double beam spectrophotometer, blank solution or reference solvent can be mounted along with test sample in a separate cuvette. In this spectrophotometer, the monochromatic light is allowed to alternatively pass across each cuvette and this reduces the time and effort required to perform the measurements unlike the single beam spectrophotometer.

Sources of error are minimized since light acts as constant source for each measurement unlike detector response drift error that leads to sources of error in single beam spectrophotometer.
