Spectrophotometry Applications In Chemistry
overall review score: 4.7
⭐⭐⭐⭐⭐
score is between 0 and 5
Spectrophotometry in chemistry is an analytical technique that measures the absorption or transmission of light by a chemical substance at specific wavelengths. It is widely used for qualitative and quantitative analysis of compounds, determining concentration levels, studying reaction kinetics, and identifying unknown substances. The method is valued for its sensitivity, simplicity, and speed, making it a fundamental tool in chemical laboratories and research.
