JordanBenedict's solution is commonly used to test for the presence of glucose or sugar in a sample. It changes color from blue to green, yellow, orange, or red depending on the concentration of glucose present. The test is based on the reduction of copper (II) ions to copper (I) ions by reducing sugars.

Is iodine an indicator of glucose?
Iodine is not an indicator of glucose. Iodine is primarily used as an indicator for the presence of starch in a solution through the formation of a blue-black color complex. Glucose can be tested using methods such as Benedict's solution, Fehling's solution, or glucose test strips.
What chemical indicator is used to test for monosaccharide?
Benedict's solution is commonly used as a chemical indicator to test for the presence of monosaccharides. It changes color from blue to green, yellow, orange, or red in the presence of reducing sugars such as glucose and fructose.
What is a 2 hour post prandial test?
A 2-hour postprandial test is a blood sugar test that measures glucose levels 2 hours after a meal. It is used to assess how the body responds to sugar intake and can help diagnose diabetes or monitor blood sugar control in individuals with diabetes.
Why is the Benedict test not exclusive to glucose?
The Benedict test is not exclusive to glucose because it can detect the presence of reducing sugars in general. This means that it can also detect other reducing sugars such as fructose, lactose, and maltose, in addition to glucose. The test relies on the reduction of Cu(II) to Cu(I) in the presence of reducing sugars, forming a colored precipitate.
When you mix sugar and a universal indicator what colour does it become?
When sugar is mixed with universal indicator, it typically does not change color as the indicator is primarily used to measure pH levels in solutions, not sugar content. The indicator will only change color based on the acidity or alkalinity of the solution it is in.
