Q
Q: In UV-Vis spectroscopy, what does a higher absorbance indicate about the concentration of a sample?
Solution:
According to Beer-Lambert Law, higher absorbance indicates a higher concentration of the absorbing species.
Steps: 5
Show Steps
Step 1: Understand that UV-Vis spectroscopy measures how much light a sample absorbs.
Step 2: Know that absorbance is a way to quantify how much light is absorbed by the sample.
Step 3: Learn about the Beer-Lambert Law, which states that absorbance is directly proportional to concentration.
Step 4: Realize that if absorbance increases, it means the sample is absorbing more light.
Step 5: Conclude that a higher absorbance means there is a higher concentration of the substance in the sample.
