Q
Q: In UV-Vis spectroscopy, what does a higher absorbance indicate?
Solution: A higher absorbance indicates a higher concentration of the analyte, as per the Beer-Lambert Law.
Steps: 5
Step 1: Understand what UV-Vis spectroscopy is. It is a technique used to measure how much light a substance absorbs in the ultraviolet and visible light spectrum.
Step 2: Learn about absorbance. Absorbance is a measure of how much light is absorbed by a sample.
Step 3: Know the Beer-Lambert Law. This law states that absorbance is directly proportional to the concentration of the substance in the solution.
Step 4: Realize what higher absorbance means. If the absorbance is higher, it means that more light is being absorbed by the sample.
Step 5: Connect absorbance to concentration. Since higher absorbance indicates more light absorption, it also indicates that there is a higher concentration of the analyte (the substance being measured) in the solution.
