COLORIMETRIC ANALYSIS Meaning and
Definition
-
Colorimetric analysis refers to a quantitative chemical analysis technique that measures the concentration of a substance by utilizing the absorption or reflection of light by colored solutions. In this method, the intensity of the color produced by a chemical reaction or the absorption of light by a sample is directly proportional to the concentration of the analyte, allowing for accurate and precise measurements.
Colorimetric analysis encompasses a range of methods that exploit the principles of colorimetry, which is the science of measuring and describing colors. Typically, a colorimeter or a spectrophotometer is employed to measure the intensity of the light, as these instruments can determine the wavelength-dependent absorption characteristics of a sample.
The procedure involves preparing standard solutions of known analyte concentrations to generate a calibration curve. By comparing the absorbance or reflectance of the unknown solution to that of the standard solutions, the concentration of the analyte can be determined. Varying colorimetric reagents are used based on the analyte being tested, allowing for specificity in the analysis.
Colorimetric analysis finds extensive application in fields like environmental monitoring, pharmaceuticals, food analysis, and clinical diagnostics. Due to its simplicity, speed, and cost-effectiveness, colorimetric analysis is widely utilized for qualitative and quantitative analysis of a broad range of chemicals. However, it is important to note that colorimetric analysis may be subject to interference from similar compounds, as well as factors like pH and temperature, which can affect the accuracy of the results.

Etymology of COLORIMETRIC ANALYSIS
The word "colorimetric" is derived from the combination of two words: "color" and "metric".
- "Color" is derived from the Latin word "color" meaning "color, hue, tint, or dye".
- "Metric" is derived from the Latin word "metrum" meaning "measure, rhythm, or pattern".
"Colorimetric" essentially refers to the measurement or analysis of color. It is a scientific method used to determine the concentration of a substance in a solution by measuring its color intensity or the color change it induces in a reaction. The term "colorimetric analysis" is thus a fusion of these two concepts, indicating a quantitative method of analysis based on color measurements.
