altose is actually a reducing sugar so a test for reducing sugar could be carried out.
1)Add 2cm3 of Benedict's solution to 2cm3 of maltose solution in a test tube and shake.
2)Leave the test tube in a beaker of boiling water for 5 minutes.
Observations:
1)blue solution to green mixture- conclude that there are traces of reducing sugar
2)blue solution to yellow or orange precipitate- conclude that there are moderate amt of reducing sugar
3)blue solution to brick red precipitate- conclude that there are large amt of reducing sugar

Will Maltose produce a positive Benedict's test?
Yes, all monosaccharides do.
What conclusion can you draw when an experimental sample gives both a positive starch and a positive maltose test after incubation?
The maltose positive test will have a degree of how positive, it is. That will tell you how much of the starch has been digested.
What conclusions can you draw when an experimental sample gives both a positive starch test and a positive maltose test after incubation?
Starch digestion (hydrolysis) is incomplete
What is the color change of maltose in a Benedict's test?
A red precipitate is formed.
What do we use to test for simple sugar egmaltose?
We use a fermenting process to test for simple sugar like maltose.
Why is Benedict's test unreliable?
its because Benedict's test only gives a possible test for reducing sugars (all monosaccharides, maltose and lactose).
Would you be able to distiguish maltose from lactose in a unknown sample from doing barfoed's test?
Both maltose aswell as lactose are disaccharides, where maltose is made up of two glucose units, whereas lactose is made up of 1 unit of glucose and 1 unit of galactose. Barfoed's test answers only for mono and disaccharides. Presence of red precipitate would indicate a positive result for monosaccharides. Thus doing Barfoed's test does not distinguish between maltose and galactose since both are disaccharides.
which of the different carbohydrates test would give a positive result for maltose describe its color change?

Is maltose non reducing sugar?
maltose is a reducing sugar ..
Is maltose an oligosaccharide?
Maltose is a disaccharide.
What is maltose dextrin?
dextrine and maltose are byproduct of starch when starch is completely hydrolized it gives dextrin and maltose
What the product to the reactants maltose and water?
Maltose and water react to form the maltose solution. A sweet solution!
