What is Benedict's Test and its Principle?
This test is answered by all reducing sugars with a free aldehyde or ketone groups. Monosaccharides possess a free aldehyde or ketone group and thus answer this test.
Principle
Is the same as Fehling's test. The difference is in the alkali. In this test, sodium carbonate produces a mild alkaline medium instead of the strong alkaline medium produced in Fehling's test.
