brown
Benedict's reagent is originally blue in color.
brown
Benedict's reagent starts off light blue. (from the copper(II) sulfate) As glucose levels in the solution rise the color will proceed as follows: green, yellow, orange, red and brick red The brown/red color comes from the formation of copper(I) oxide an insoluble precipitate.
You can determine if a liquid resembling water contains glucose through a few methods. One common approach is using a glucose test strip, which changes color in the presence of glucose. Another method is conducting a Benedict's test, where the liquid is heated with Benedict's reagent, and a color change indicates the presence of reducing sugars like glucose. Additionally, advanced techniques such as chromatography or spectrophotometry can also identify glucose in a solution.
blue
Benedict solution is the chemical indicator for simple sugars.
The same color as Pope Benedict after he was exhumed.
Amylase does not change color when reacting with Benedict's reagent. Benedict's reagent is mainly used to test for reducing sugars like glucose, which would turn from blue to brick-red when reacting with the reagent. Amylase is an enzyme that breaks down starch into smaller sugars, but it does not directly react with Benedict's reagent to produce a color change.
The positive reaction color for simple sugars like glucose in Benedict's test is a brick-red precipitate. This color change indicates the presence of reducing sugars, which react with the copper ions in Benedict's solution to form the red precipitate.

A negative reaction for Benedict's test would be no color change or a very faint color change after adding the Benedict's reagent to a sample containing reducing sugars. This would indicate that there is a low concentration or absence of reducing sugars in the sample.
