What color does saliva turn into with the Benedict's solution?
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.)
Why does a cooked rice with Benedict's solution change its color when it is heated?
Benedict Solution is use to check the presence of Saccharides in food by changing the specimen's color like cooked rice when it puts a few drops of Benedict solution it change its color as yellow green. It means there is a presence of sugar in rice. About the Saliva thing, (Benedict Solution+Saliva+Cooked Rice) Saliva breaks the sugar into fragments so it helps the Benedict Solution to find the presence of sugar in rice, So it makes more yellow green than without Saliva one
What happened to the starch solution after you have added saliva?
Saliva contains enzymes which catalyse the breakdown of starch to maltose and dextrin. If starch solution is treated with saliva, these simpler sugars will soon start to form, which means the mixture will give the Benedict's test.

Why did a solution of saliva and oats test positive with benedict's test and iodine test if the oats alone tested positive only in the iodine test and the saliva alone was negative for both?
polysaccharides and simple sugar

Testing saliva with litmus paper - what does it mean?
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 color red litmus put 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.
