Q: In a UV-Vis spectrum, what does a higher absorbance value indicate?

Solution: A higher absorbance value in a UV-Vis spectrum indicates a higher concentration of the analyte, according to Beer-Lambert law.

Steps: 5

Step 1: Understand what a UV-Vis spectrum is. It is a graph that shows how much light a substance absorbs at different wavelengths.
Step 2: Know that absorbance is a measure of how much light is absorbed by the substance.
Step 3: Learn about the Beer-Lambert law, which states that absorbance is directly related to the concentration of the substance in a solution.
Step 4: Realize that if the absorbance value is higher, it means that more light is being absorbed.
Step 5: Conclude that a higher absorbance value indicates a higher concentration of the substance (analyte) in the solution.
