What else can I help you with?
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.
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.
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

Which is more sensitive test fehlings test or Benedicts test?
Benedict's test is more sensitive than Fehling's test for detecting reducing sugars in a sample. Benedict's reagent has a lower detection threshold and is known to give more accurate results compared to Fehling's reagent.
What is a good conclusion of the benedicts test?
A good conclusion of the Benedict's test would be to state whether the test result was positive or negative for reducing sugars. Positive result would indicate the presence of reducing sugars, while a negative result would suggest their absence. This information can be important for further analysis or identification of certain carbohydrates.
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 are the Benedicts test results for glucose?
Benedict's test is a simple chemical test used to detect the presence of reducing sugars like glucose in a solution. The test result is positive if a brick-red precipitate forms, indicating the presence of reducing sugars. If the solution remains blue, it indicates a negative result.
