Would glucose solution produce a positive Benedicts test?
No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.
What is the indicator and color change for a positive test for glucose?
Benedict solution is the chemical indicator for simple sugars.
When a non reducing sugar is tested with Benedict's reagent?
Non reducing sugars do not react with Benedict's reagent. After the test, sample without reducing sugars remains the same, blue.When reducing sugars are present in the sample, we can consider four results after the test is completed: a) green, low amount, that is 0.1 to 0.5% of reducing sugars in solution; b) yellow, low amounts of reducing sugars, 0.5 to 1.0%; c) orange, moderate content of reducing sugars, 1.0 to 1.5% of reducing sugars present; and c) brick red, large amount of reducing sugars in solution, 1.5 to 2.0%.
What is a sugar compound?
Sugars are a group of compounds carbohydrates, and are built of cyclic compounds. Simple sugars are called monosaccharides have just one ring, disaccharides have two fused by an "ether" link. and are Table sugar is sucrose a disaccharide made of two linked monosaccharides glucose and fructose, C12H22O11
Why is lemonade made from a powdered mixture a solution and not a suspension?
Because the sugars and salts and various chemicals (if present) actually dissolve. Hence, it is a solution.
What are nonreducing sugars?
reducing sugars are those sugars which cannot donate electron and cannot reduce other solution
What is the indicator for simple sugars?
Benedict's Solution

What is the reagent used to test for complex sugars?
benidict's solution
What is the difference between iodine solution and Benedict's solution?
Benedict's solution is used to test for simple sugars and iodine is used to test for starches.
What is the indicator and color change for a positive test for glucose?
Benedict solution is the chemical indicator for simple sugars.
What is Benedict's solution used for?
Benedict's solution is most commonly used for testing if sugars are present in any enzyme, or solution, that contains starch. ex. Water + Starch Then test for sugars with benedict's.
How would you determine whether milk has reducing sugars?
Test it with Benedict's solution.
What is the test for non-reducing sugars?
Benidicts Solution, Wont change colour

What test is used to test for sugars in a food?
Benedict's test using Benedict's Solution.
