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.

Secondary Uses

  1. Identification of carbohydrate content in unknown samples:
     Used to confirm the presence of reducing sugars in plant extracts, juices, or hydrolyzed polysaccharides. 
  2. Routine qualitative analysis in food chemistry labs:
     Applied in basic food testing kits and protocols to check sugar levels in various food products. 
  3. Historical method reference in pharmaceutical analysis:
