What is the role of a solvent in UV-Vis spectroscopy?
To enhance the absorption of light
To provide a medium for the sample
To scatter light for better detection
To change the wavelength of light
The solvent serves as a medium for the sample, allowing light to pass through and interact with the analyte without interfering with the measurement.

Q
Q: What is the role of a solvent in UV-Vis spectroscopy?
Solution: The solvent serves as a medium for the sample, allowing light to pass through and interact with the analyte without interfering with the measurement.
Steps: 5
Step 1: Understand that UV-Vis spectroscopy is a technique used to measure how much light a sample absorbs.
Step 2: Recognize that a solvent is a liquid that dissolves the sample (analyte) so it can be tested.
Step 3: Know that the solvent must be transparent to UV and visible light, allowing the light to pass through.
Step 4: Realize that the solvent should not absorb light in the same range as the analyte to avoid interference.
Step 5: Conclude that the solvent helps create a clear path for the light to interact with the sample, enabling accurate measurements.
