Questions & Step-by-Step Solutions

What is the primary application of UV-Vis spectroscopy in analytical chemistry?
  • Step 1: Understand that UV-Vis spectroscopy is a technique that uses ultraviolet and visible light.
  • Step 2: Know that this technique measures how much light is absorbed by a solution.
  • Step 3: Learn that different substances absorb light at specific wavelengths.
  • Step 4: Realize that by measuring the absorbance at these wavelengths, we can determine how much of a substance (analyte) is present in the solution.
  • Step 5: Conclude that the primary application of UV-Vis spectroscopy is to quantify the concentration of analytes in solution.
