Q: Which instrument is commonly used to measure the absorbance of a sample in UV-Vis spectroscopy?
Solution: A spectrophotometer is the instrument used to measure the absorbance of a sample in UV-Vis spectroscopy.
Steps: 4
Step 1: Understand what UV-Vis spectroscopy is. It is a technique used to measure how much light a sample absorbs in the ultraviolet and visible light spectrum.
Step 2: Identify the purpose of measuring absorbance. Absorbance helps determine the concentration of a substance in a sample.
Step 3: Learn about the instrument used for this measurement. The instrument that measures absorbance is called a spectrophotometer.
Step 4: Know that a spectrophotometer shines light through a sample and measures how much light is absorbed.
