a solution of fuchsine decolorized by treatment with sulfur dioxide that gives a useful test for aldehydes because they restore the dye's color — compare feulgen reaction.
Schiff's reagent is used to distinguish between aldehydes and ketones. Ketones do not react with Schiff's reagent; however, aldehydes react with Schiff's reagent. Complete answer: The Schiff test is a chemical test used to check the presence of aldehydes in a solution.
Schiff Reagent? Schiff reagent is the product formed in some dye formulation reactions such as the reaction between sodium bisulfite and fuchsine. It is used to check for the presence of aldehyde in an analyte. It can be used to differentiate between aldehyde and ketones.
The Schiff test is a chemical test used to check for the presence of aldehydes in a given analyte. This is done by reacting the analyte with a small quantity of a Schiff reagent (which is the product formed in certain dye formulation reactions such as the reaction between sodium bisulfite and fuchsin).
