Fehlins test is done to identify aldehides. Fehlins solution is used for this test. If aldehides are added to this soluton, a red precipitate is formed.
The DNA test result is positive.
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.
the color of a positive test results is bright green
A positive result for the Sakaguchi test is the formation of a white or yellow precipitate in the presence of arginine or histidine in the test sample. This precipitate forms when ninhydrin (reagent used in the test) reacts with the guanidine group of arginine or the imidazole group of histidine.
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
Fehling test is used for reducing sugars.
ulo nyo!!
The DNA test result is positive.
The crystal violet test result is positive.
"Did you get a positive hCG test strip result?"
yes,it give positive test
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.
A pregnancy test can show a positive result if you have miscarried. There is still enough hormone in your body to produce a positive result.
RED
Any amount of Vyvanse could result in a positive amphetamine test.
all carbohydrates show positive result to Molisch test. this is because Molisch test is used to distinguish carbohydrates from other organic compound.
I mean widal test result positive after treatment
