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
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 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.
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
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 is more sensitive test fehlings test or Benedicts test?
benedicts test
What are the Benedicts test results for glucose?
the solution will turn a 'brick red' colour if positive but will stay blue if negative.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
What test show hydrolysis of proteins?
benedicts test
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
What are the Benedicts test results for Gatorade?
penis
What is the test for sugar using Benedicts solution?
prosrdure of benidect solution test
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.
Does using benedicts reagent on honey produce a positive result?
yes
Why is the Benedict's test is positive when water starch and HCl keep for 30mins?
benedicts test is positive when water starch and HCL keep for 30 mins because glycosidic linkages between amylose and amylopectin breaks and free ends are available to react with Benedict reagent
