Answer:
Reagents are used in many reactions in chemistry.
Explanation:
1) Bayer’s Reagent –
1% alkaline solution of KMnO[tex]_{4}[/tex] is known as Bayer’s Reagent.
USES
Unsaturated hydrocarbon gives a positive test from the reagent. The purple color of the reagent changes to the colorless solution when any alkene and alkynes are present.
2) Dimethyl glyoxime reagent –
The reagent is a popular chelating regent with molecular formula – C[tex]_{4}[/tex]H[tex]_{8}[/tex]N[tex]_{2}[/tex]O[tex]_{2}[/tex]
USES
Used in gravimetry for the determination of nickel, palladium, and platinum, many other metals.
3) Fehling’s solution –
It is a blue-colored solution of Rochelle salt and copper sulfate.
USES
Fehling’s solution is used to distinguish between aldehyde and ketone.
Aldehyde gives a positive test and ketone gives a negative test except for α – Hydroxy ketones.
