What is the primary purpose of the 3 Step Extraction method?

The primary purpose of the 3 Step Extraction method is to react a specimen with reagents to produce a color change. This method is particularly valuable in various chemical and analytical processes, as observing a color change can indicate the presence or concentration of specific compounds within a mixture. Such colorimetric reactions are often utilized in analytical chemistry to help identify substances through visual observation or spectrophotometric analysis.

Using reagents that produce a distinct color change allows analysts to infer important information about the chemical properties of the specimen, which can be critical in forensic analysis, quality control, and other scientific investigations. The 3 Step Extraction method typically involves a series of deliberate chemical treatments to facilitate this reaction, thus making it an effective tool in the identification and quantification of compounds in a sample.
