Fehling Solution 1 and 2 Extra Pure
Original price was: $ 35.20.$ 35.09Current price is: $ 35.09.
Fehling Solution 1 and 2 Extra Pure are essential reagents in classical laboratory chemistry, particularly used for the qualitative detection of reducing sugars such as glucose.
- Fehling Solution 1 contains copper(II) sulfate, while
- Fehling Solution 2 contains an alkaline potassium sodium tartrate (Rochelle salt) solution.
When mixed in equal parts just before use, they form a deep blue complex that, upon heating with a reducing sugar, yields a brick-red precipitate of cuprous oxide, confirming the presence of aldehyde groups.
These solutions are highly valuable in educational labs, food testing, and biochemical experiments. Store them separately in cool, dry conditions, and always mix fresh for accurate results.
Fehling Solution 1 and 2 Extra Pure
Primary Uses
- Detection of reducing sugars:
Widely used in qualitative analysis to test for the presence of aldehyde functional groups, especially in reducing sugars like glucose. - Differentiation between aldehydes and ketones:
Reacts with aldehydes to form a red precipitate of copper(I) oxide, while ketones generally do not react. - Educational experiments in redox chemistry:
Demonstrates redox reactions and the principle of oxidation-reduction using visible color change.
