Questions & Step-by-Step Solutions

In UV-Vis spectroscopy, what does a higher absorbance indicate about the concentration of a sample?
  • 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.
