Milk typically does not produce a positive result in the Benedict's test because it contains primarily lactose, which is a non-reducing sugar. The Benedict's test is designed to detect reducing sugars, such as glucose and fructose, that can donate electrons and reduce copper(II) ions to form a precipitate. While lactose can be hydrolyzed into glucose and galactose, in its intact form, it does not exhibit reducing properties that would yield a positive result in the test.

Do eggs test positive in benedicts test?
Yes, eggs can test positive in the Benedict's test because they contain glucose, which is a reducing sugar that reacts with the reagent in the test to form a colored precipitate.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
What substrate gives a positive reaction for benedicts reagent?
Reduction of Benedict's reagent occurs with reducing sugars such as glucose, fructose, and galactose, giving a positive test result. This test is used to detect the presence of reducing sugars in various food products.
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.
Do eggs test positive in benedicts test?
Yes, eggs can test positive in the Benedict's test because they contain glucose, which is a reducing sugar that reacts with the reagent in the test to form a colored precipitate.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
Will hydrolysed dextrine give positive response to Benedict test?
Yes, it should. Benedicts test will be positive for reducing sugars, and since glucose is such a sugar, and would be a product of dextrin hydrolysis, you should get a positive result with Benedicts reagent.
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
Does skim milk test positive with the benedict's test?
yes
What are the Benedicts test results for Gatorade?

What substrate gives a positive reaction for benedicts reagent?
Reduction of Benedict's reagent occurs with reducing sugars such as glucose, fructose, and galactose, giving a positive test result. This test is used to detect the presence of reducing sugars in various food products.
What is the test for sugar using Benedicts solution?
prosrdure of benidect solution test
Is iodine give positive test for skim milk?
Iodine does not give a positive test for skim milk. Instead, iodine is typically used to test for the presence of starch, which is not found in significant amounts in skim milk. If iodine is added to skim milk, it would not change color, indicating that starch is absent. Therefore, the iodine test is not applicable for detecting components in skim milk.
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.
Can your baby test positive for opiates by drinking mothers breast milk?
no
List of carbohydrates that is positive to Molisch Benedicts Barfoeds Seliwanoffs Bials and Fermentation tests?
Glucose, fructose, maltose, sucrose, lactose, and starch are carbohydrates that would likely test positive in Molisch, Benedict's, Barfoed's, Seliwanoff's, Bial's, and fermentation tests. These carbohydrates are commonly used in biochemical testing due to their distinct reactivity with the specific reagents in each test.
