What is the chemical structure of Tollen's reagent?
Tollen's reagent is usually ammoniacal silver nitrate. Even in other variations it consists of an aqueous diaminesilver (I) complex. This diaminesilver (I) complex acts as an agent. This when placed in a test tube forms a silver mirror. Tollen's reagent is generally ammoniacal silver nitrate. But it could be other reagents as well, as long as the complex diamminesilver(I) complex ion [Ag(NH3)2]+ can be generated.
What happen when you react sugar like glucose and fructose with tollen' s reagent and the Fehlings solution?
Glucose oxidizes very quickly, and creates a silver mirror layer between the glucose solution and the Tollens' reagent. This is because of how the ketose reacts and reduces the silver molecules in Tollen's reagent.
How do you prepare chromic acid reagent?
alwase
How do you prepare kedd's reagent?
card. + Kedde's reagent (3,5- dinitrobenzoic acid + NaOH → violet colour.
How do you prepare organometallic compounds?
By using grignard reagent
Why can't you prepare and store tollens' reagent in advance for tests?
Tollen's reagent will dry out if un-used. Also Tollen's reagent contains the complex Ag(NH3)2 OH, which is explosive when dry.
What is tollen's reagent and baeyer's reagent?
tollen's reagent = [Ag(NO)2]+ baeyer's reagent= KMnO4
What are the components of tollens reagent?
tollen reagent
What is formula of tollens reagent?
2[Ag(NH3)2]OH is tollen's reagent
How can you prepare borsches reagent in the lab?

How do you detect glucose in a plant's leaf?
In order to detect glucose in a plant's leaf, you will need several items, including leaves, a beaker, a boiling tube, Tollen's reagent, and Fehling's reagent. If the leaf contains glucose, the test-tube containing the Tollen's reagent will turn a silver color.
Do carboxylic acids or alpha-hydroxy ethers also give tollen 's reagent test?
yes...

What monocarboxylic acid is oxidized by the tollen's reagent?
aldehydes oxidized to monocarboxylic acids... CH3-CHO +(O) = CH3-COOH
The role of ammonia in Tollen's reagent?
Ammonia is used as a ligand in order to dissolve the insoluble Silver ions under alkaline conditions.
