Q: What is the purpose of using a blank in UV-Vis spectroscopy?
Solution:
A blank is used to account for the absorbance of the solvent, ensuring that only the sample's absorbance is measured.
Steps: 5
Show Steps
Step 1: Understand that UV-Vis spectroscopy measures how much light is absorbed by a sample.
Step 2: Know that the sample is usually dissolved in a solvent (like water or ethanol).
Step 3: Realize that the solvent can also absorb some light, which can affect the results.
Step 4: Use a blank, which is just the solvent without the sample, to measure how much light the solvent absorbs.
Step 5: Subtract the absorbance of the blank from the absorbance of the sample to get the true absorbance of the sample only.
