What technique(s) in spectrophotometry would use to determine the identity of matter?
A. Qualitative
b. Quantative
c. Any technique is useful
Spectrophotometry is a technique used to measure the interaction of light with matter. It is widely used in analytical chemistry, biochemistry, and other scientific fields to determine the concentration of a substance in a sample and to identify unknown substances. Spectrophotometry can be qualitative or quantitative, depending on the type of information being sought. In qualitative spectrophotometry, the goal is to identify the composition of a sample, while in quantitative spectrophotometry, the goal is to determine the concentration of a substance in a sample. Both techniques can be useful in determining the identity of matter, and the choice of technique may depend on the specific question being asked and the information available.
