Benedict's solution changes colors (blue to green to yellow to orange to red) in the presence of "reducing" sugars, which are not normally present in saliva. An interesting experiment, however, is testing table sugar with Benedict's solution. Table sugar is a glucose sugar joined to a fructose sugar, so they cannot react with the Benedict's solution and no color change occurs. Put table sugar in your mouth for a few moments, and then test the saliva. Now the Benedict's solution will react! (The reason: saliva has an enzyme, amylase, which breaks the glucose and fructose apart so that they can react to the Benedict's.)

What color does Benedicts solution turn when mixed with simple sugars?

What are the Benedicts test results for glucose?
the solution will turn a 'brick red' colour if positive but will stay blue if negative.
What is the color of a solution when starch is added?
Benedicts tests for the presence of monosaccharides. It will turn a yellow to red color if it is a positive test, but it does not so starch does not contain monosaccharides. ...Actually..... If starch is heated at 250 degrees Celsius, it breaks down into sugar! a saccharide! The intense heat denatures the the starch and transforms it into sugar. Also, if you have starch and amylase ( enzyme found in your saliva) and heat that to 37 degrees Celsius, you will also get a sugar, but in the form of glucose!
What color does litmus paper turn when diped in saliva?
Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.

What is the stain solution when chemical is test for sugar?
It is normally benedicts solution. Add about 1/4 of the total sugar solution to a test tube and heat it in a hot water bath at around 50 degrees C for 5 min. For example, heat 40mL of sugar water (C12H22O11 aq ) with 10mL of Benedicts soluton (copper and sodium salts). If it is a positive test it will turn yellow.

What color does sugar turn when you add iodine to it?
Iodine test is a procedure that tells whether a certain element or the such contains starch (or sugar) in it.In this test, we add iodine solution (with, possibly, KI reagent) to a material [in your case, sugar]. If starch ispresent, a blue-black, somehow purple, color will result, changing the initial color of iodine. If starch amylase (sugar) is NOT present, the color will remain orange/yellowish.
In which color does bases turn turmeric into?
Bases turn turmeric into red color, whereas acids and neutrals do not have any affect on the solution (it remains yellow in color).
