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.
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.
What color does potassium show in a flame test?
Lilac or Violet. Lithium ; Red Sodium ; Yellow Copper ; Blue/Green Barium ; Pale Green. Are some of the ccommon flame colours. There are many more flames test colours for different elements.
What test show hydrolysis of proteins?
The biuret test can be used to show the hydrolysis of proteins. In this test, a blue to purple color change indicates the presence of peptide bonds being hydrolyzed. This color change occurs due to the formation of a coordination complex between copper ions and the peptide bonds.
Are substance considered reducing fehlings test also the substance reducing in benedicts test?
yes.

Why should you add 8 drops of urine in the Benedict test?

What does a negative Benedicts test indicate?
A negative Benedict's test would indicate that there isn't any presence of reducing sugars in that particular substance.
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.
Why Benedict test is semi quantitative?
Benedicts solution changes through a range of colours (blue, green, orange, red) according to how much reducing sugar is present in the sample. This can be used to give a rough answer to the question "How much sugar is in the sample?", but is not accurate enough (because of the blending between one colour and the next), to be called a quantitative test.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
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.
Who sells Benedect test solution?
Most chemical supply companies sell it. You can do an internet search for "retail sale of Benedicts solution".
Which indicator would most likely yield a positive test by way of a color change in the water-cookie solution?
Benedicts solution
