What else can I help you with?
After hydrolysis did sucrose give a positive test with fehlings test why orwhy not?
Sucrose would not give a positive test with Fehling's reagent after hydrolysis because sucrose is a non-reducing sugar. During hydrolysis, sucrose is broken down into its monosaccharide components (glucose and fructose), which are reducing sugars and can react with Fehling's reagent to give a positive test for reducing sugars.
Which substance will give a red precipitate when heated with Fehling solution?
Cu2O gives red ppt when heated with fehlings soln
What group of substance that give positive reaction to molisch test?
Carbohydrates typically give a positive reaction to the Molisch test. This is because the Molisch reagent reacts with the carbohydrates to form a purple complex, indicating the presence of sugar molecules in the solution.
Will Ultram test positive for cocaine?
No, there is only one drug with a valid use that can give a false positive for cocaine. Cocaine-hydrochloride topical solution. It is used by eye and throat surgeons as an anesthetic.
Will lipids give positive result from Benedict's solution?
No, lipids will not give a positive result with Benedict's solution. Benedict's test is used primarily to detect reducing sugars, such as glucose and fructose, by forming a colored precipitate when heated in the presence of these sugars. Lipids do not contain the necessary functional groups that react with Benedict's reagent, so they do not produce a color change.
Which compounds will give you a positive bromine test?
Alkenes and alkynes will give a positive bromine test. The reddish-brown color of a bromine solution will be decolorized upon reaction with an alkene or alkyne due to the formation of a colorless dibromo compound.
Why dont polysaccharides give a positive test with Fehling's solution?
Fehling test is only suitable for reducing sugars, that means, monosaccharides in its open form with an aldehyd available. Polysacchardes have the aldehydes in a acetal form and they can not react
How do you solve 5z2 44z 32?
(5z - 4)(z - 8) is the solution if the term 44z is negative (5z + 4)(z + 8) is the solution if 44z is positive. It's easier to give a definitive answer if the question is accurately stated.
What colour will the DCPIP test give if it is positive?
If the DCPIP test is positive, the solution will change from blue to colorless or clear. This color change indicates the reduction of DCPIP by a reducing agent present in the sample being tested.
Can A positive give blood O positive?
no
Did gelatin give positive result with xanthoprotic test?
yes,it give positive test
Can you give me a solution for this?
for what?
