Q: In UV-Vis spectroscopy, what does the Beer-Lambert law relate?
Solution: The Beer-Lambert law relates absorbance to concentration, indicating that absorbance increases linearly with concentration of the absorbing species.
Steps: 6
Step 1: Understand that UV-Vis spectroscopy is a technique used to measure how much light is absorbed by a solution.
Step 2: Know that the Beer-Lambert law is a formula that helps us understand the relationship between absorbance and concentration.
Step 3: Absorbance is a measure of how much light is absorbed by the solution.
Step 4: Concentration refers to how much of the absorbing substance is present in the solution.
Step 5: The Beer-Lambert law states that as the concentration of the absorbing substance increases, the absorbance also increases.
Step 6: This relationship is linear, meaning if you double the concentration, the absorbance will also double.
