Why anthrone reagent needs to be kept cold before using?
Anthrone reagent is prepared in concentrated sulfuric acid. Adding reagents to acid causes immediate dissociation of the reagent and releases heat. If your solution weren't cold, it could generate enough heat to blow out of the flask or bottle.
What is an Anthrone test?
An Anthrone Test is a test that discovers the amount of sugar in the given sample. This colorimetric test causes a blue-green color to appear in the sample where sugar is present.
How many RPM and time needed to centrifuge sample in Total Carbohydrate Determination by Anthrone Method?
10,000 rpm for 8 min is good for anthrone method to estimate total sugars in the sample
What is anthrone test for carbohydrates?
The Antrone test is a general test for carbohydrates (like the Molisch test). Thus, all carbohydrates should yield a positive test (green precipitate) in the anthrone reaction.
What is the function of nessler's reagent?
nessler's reagent
What is the procedure to prepare anthrone reagent?
0.2% of anthrone was dissolved in 100ml of conc H2SO4.

Substances which are ve to anthrone test?
The anthrone test, tests for carbohydrates. The positive indicator is glucose since glucose is one of the most common monosaccarides and is found in many polysaccarides. Anthrone tests positive for fructose, ribose, maltose, and sucrose.
What is the chemical basis of the Anthrone test?
carbohydrates
