Ammoniacal AgNO

Reduction of ammoniacal silver nitrate. Add a few drops of a neutral solution of a formate to ammoniacal AgNO (see Test 4, p. 342). A silver mirror or more usually a grey precipitate of metallic sih er is produced on boiling. 

Does not reduce ammoniacal AgNO, solution cf. tartaric acid)... 

Problem 8.46 Deduce the structural formula of a compound of molecular formula C H, which adds 2 mol of H, to form 2-methylpentane, forms a carbonyl compound in aqueous HjSO -HgSO solution and does not react with ammoniacal AgNO, solution, [Ag(NH3)j) NO. ... 

NAGu reduces Fehling s soln with the formation of an expl copper salt, it also reduces an ammoniacal AgNOs soln with the formation of an expl silver salt and some gases(See under Nitr ami noguanidine Salts)... 

Silver salt, black ppt was prepd by adding while stirring an aq soln of ammoniacal AgNO (2 mols) to a hot aq soln of N,N -dichloro-azodicarboxamidine, A dark red ppt forms immediately, but it turns black on continued stirring at 90°- In order to decrease the sensitiveness to friction, the salt may be Co-precipitated with materials such as dextrin Refsi 1) L.A. Burrow S, USP 2086533(1937)... 

Brownish-yellow needles with a bluish cast, mp 128s. bp above 360 . Slightly sol in water freely sol in ale, benzene, chloroform, ether, It reduces alcoholic ammoniacal AgNO. ... 

Ag—AS staining AgNOs, followed by ammoniacal AgNOs and formalin Light Nucleolar organiser region rRNA synthesis... 

Reduction of ammoniacal silver nitrate. Add i drop of dil. NaOH solution to about 5 ml. of AgNO, solution, and add dil. NH solution drop by drop until the silver oxide is almost redissolved. Add AgNO, solution until a faint but permanent precipitate is obtained (see p.525). Then add 0 5 ml. of a neutral tartrate solution. Place the tube in warm water a silver mirror is formed in a few minutes. 

AgNO, and the addition of caustic soda will cause the base to separate (if insoluble) as solid or liquid, oi, if the base is olatile, n ill produce a strong ammoniacal smell. The furtliei examination of the base is the same as that described under I, 2. Acid chlorides are usually insoluble in water, but rapidly decompose, and may pass into solution as the fiee acid, giiing at the same time fi ee hydrochloric acid. 

Taylor Rinkenbach( Ref 4) investigated four samples of silver acetylide prepd by various methods. The sample B,prepd from an ammoniacal soln of AgNO. gave an impact sensitivity with 0.5kg wt 15 cm(LA 43 cm) expln temp 177 LA 383°) and pendulum friction values, fall 33 cm and number of swings 4(for LA 37.5 cm and 12 swings)... 

A 100.0-mL sample of brackish water was made ammoniacal, and the sulfide it contained was titrated with 16.47 mL of 0.02310 M AgNOs. The analytical... 

Cyanide may be determined by titration in an ammoniacal iodide solution with standardized AgNOs, using the opalescence of Agl as the endpoint The NH3 prevents the temporary, local precipitation of Ag[Ag(CN)2]. The main reactions are ...
