colorimetric analysis

Colorimetric analysis is a technique used to measure the concentration of a substance in a solution by analyzing its color. When a chemical reacts, it may produce a color change that can be quantitatively assessed. By shining light through the solution and measuring how much light is absorbed by the colored solution, we can determine the concentration of the substance. This method is widely used in laboratories, such as testing for pollutants in water or assessing nutrient levels in plants, as it provides a simple and effective way to obtain data based on color intensity.
