Questions & Step-by-Step Solutions

What type of information can be obtained from a UV-Vis spectrum?
  • Step 1: Understand that a UV-Vis spectrum is a graph that shows how much light a substance absorbs at different wavelengths of ultraviolet and visible light.
  • Step 2: Recognize that the peaks in the spectrum indicate specific wavelengths where the substance absorbs light.
  • Step 3: Learn that the position of these peaks can give clues about the molecular structure of the substance, such as the types of bonds present.
  • Step 4: Note that the height or area of the peaks can be used to determine the concentration of the substance in a solution.
  • Step 5: Identify that certain patterns in the absorbance can indicate the presence of specific functional groups, like alcohols or carbonyls.
