Final answer:
In a Schiff test, a color change from colorless to magenta indicates the presence of amines.
Step-by-step explanation:
In a Schiff test, a color change from colorless to magenta indicates the presence of amines.
The Schiff test is a chemical test used to detect the presence of amines. Amines are organic compounds that contain a nitrogen atom bonded to one or more carbon atoms. When an amine reacts with Schiff reagent, a color change occurs, turning the solution from colorless to magenta. Other compounds, such as alcohols, carboxylic acids, and esters, do not produce this color change.
