[Co(NH3)3Cl3] does not give a precipitate with AgNO3 solution because in it all the chlorine atoms are attached by secondary valencies.
What reacts with Ammonical AgNO3?
The Compound ′X′ reacts with ammonical AgNO3 to give a white precipitate and on oxidation with hot alkaline KMnO4 gives the acid (CH3)2CHCOOH .
What does a white precipitate indicate?
AgNO3 solution is often used in a similar way to test for halide ion. If AgNO3 solution is added to an acidified unknown solution, a white precipitate indicates the presence of Cl– ions, a cream-colored precipitate indicates the presence of Br– ions, and a yellow precipitate indicates the presence of I– ions.
Which of the following compound readily reacts with ammonia Kal silver nitrate solution?
Aldehydes (acetaldehyde and formaldehyde) reacts with Tollen’s reagent (ammoniacal silver nitrate solution) to form a silver mirror.Which of the following gives white precipitate with ammonia?

Which halide does not give any precipitate when warmed with alcoholic AgNO3?
The halide which does not give precipitate when warmed with alcoholic AgNOs solution is 1) Chlorobenzene 11.
What forms a white precipitate with HCl?
If any lead ion is present, addition of cold HCl solution to the liquid will cause white lead chloride to precipitate.
Is white precipitate a solid?
Precipitates of carbonate ion, colours From alkali metals, only lithium forms insoluble carbonate. Li2CO3 is a white solid precipitate compound. All alkaline earth metals forms insoluble carbonate. Also, all 3d metal cations’ carbonates are insoluble in water.
What happens when acetylene reacts with AgNO3?
When acetylene gas is passed over ammoniacal silver nitrate soln gives white ppt of disilveracetylide is formed. – When acetylene is passed over ammoniacal silver nitrate solution, white ppt of disilveracetylide is formed. Hope this helped you.
What happens when a ethyne reacts with Ammonical silver nitrate?
C2H2 + 2AgNO3 + 2NH4OH –> C2Ag2 + 2NH4NO3 + 2H2O It is called Tollen’s Test.
Which of the following react with ammoniacal cuprous chloride?
-Therefore, the compound which reacts with ammoniacal cuprous chloride which produces a red precipitate is ethyne (acetylene). Thus, the answer is option (C) Ethyne.
Which of the following does not give white precipitate with a monocle AgNO3?
Chloroform is a chlorine compound, but it does not give white precipitate with silver nitrate solution.
Which of the following compound readily reacts with a monocle silver nitrate solution?
(CH3)2C ≡ CH.
What gives a silver mirror with Tollens reagent?
In a positive test, the diamine silver(I) complex oxidizes the aldehyde to a carboxylate ion and in the process is reduced to elemental silver and aqueous ammonia. The elemental silver precipitates out of solution, occasionally onto the inner surface of the reaction vessel, giving a characteristic “silver mirror”.
What is the silver mirror test or tollens test explain with example?
Tollens’ test, also known as silver-mirror test, is a qualitative laboratory test used to distinguish between an aldehyde and a ketone. It exploits the fact that aldehydes are readily oxidized (see oxidation), whereas ketones are not.
Will k2 ptcl4 form precipitate with AgNO3?
Solution. It gives no chloride ion in solution, therefore, it will not form a precipitate with AgNO3 solution.
