Question: What is the purpose of using a blank sample in UV-Vis spectroscopy?

Options:

Correct Answer: To provide a reference for baseline correction

Solution:

A blank sample is used to provide a reference for baseline correction, ensuring that only the absorbance due to the analyte is measured.

What is the purpose of using a blank sample in UV-Vis spectroscopy?

Step 1: Understand that UV-Vis spectroscopy measures how much light is absorbed by a sample.
Step 2: Know that a blank sample is a solution that contains everything except the analyte (the substance you want to measure).
Step 3: Use the blank sample to measure the absorbance of the solvent and any other components in the solution.
Step 4: Subtract the absorbance of the blank from the absorbance of the sample with the analyte.
Step 5: This subtraction gives you the true absorbance due only to the analyte, allowing for accurate measurements.
