Question

Before measuring the absorbance of a solution with the Ocean Optics spectrophotometer, it is important to run a blank sample of ______ to correct for any light absorption not originating from the solute.

a. an empty cuvette
b. the solvent being used in the experiment
c. a standard solution
d. deionized water

Answer 1

b. The solvent being used in the experiment.

Step-by-step explanation:

The spectrophotometer indicates the absorption of the light for the substance. So, during the experiment, is necessary to put the solvent first, so the equipment will discount the absorption of it, and then, with the samples, will indicate the absorption of the solute.
