Nitrates silver AgNO

Urea reacts with silver nitrate, AgNO, in the presence of sodium hydroxide, NaOH, and forms a diargentic derivative (5) of a pale-yeUow color. Sodium hydroxide promotes the change of urea into the imidol form (6) ... 

Common ion effect The tube at the left contains a saturated solution of silver acetate (AgC2H302). Originally the tube at the right also contained a saturated solution of silver acetate. With the addition of a solution of silver nitrate (AgNOs), the solubility equilibrium of the silver acetate is shifted by the common ion Ag+ and additional silver acetate precipitates. 

Silver nitrate, AgNOs, is a third solid substance that dissolves in water to give a conducting solution. The reaction is... 

Some ionic compounds are soluble, others are not. Consider what happens when we pour a solution of sodium chloride (a strong electrolyte) into a solution of silver nitrate (another strong electrolyte). A solution of sodium chloride contains Na+ cations and Cl anions. Similarly, a solution of silver nitrate, AgNO, contains Ag+ cations and NO, anions. When we mix these two aqueous solutions, a white precipitate, a cloudy, finely divided solid deposit, forms immediately. Analysis shows that the precipitate is silver chloride, AgCl, an insoluble white solid. The... 

Other metallic elements form ionic compounds with cation charges ranging from -F1 to + 3. Aluminum nitrate nonahydrate, A1 (N03)3 9 H2 O, is composed of cations, NO3 anions, and water molecules. Silver nitrate (AgNO ), which contains Ag cations, is a soluble silver salt that is used in silver plating. 

Add N-acetyl homocysteine thiolactone (Aldrich) to the bicarbonate reaction mixture to obtain a concentration representing a 10- to 20-fold excess over the amount of amines present. For protein thiolation, add the same molar excess of thiolactone reagent to the water reaction medium, and then slowly add an equivalent molar quantity of silver nitrate (AgNO j). Maintain the pH at 7.0-7.5 with periodic addition of NaOH.

In this reaction, the aluminum (Al) will take the place of silver (Ag) in the compound silver nitrate (AgNOs) because aluminum is more reactive, and, therefore, above silver in the activity series.

In 2001, Rai and co-workers (114) reported a silver-mediated aziridination of olefins in THF with Chloramine-T. In their case, aprotic solvents gave better yields versus protic solvents. Then, in 2003, Komatsu and co-workers (115) used similar conditions and found no reaction in THF (solvent) while they detected 70% conversion in CH2CI2. Silver nitrate (AgNOs) was required stoichiometrically in this transformation. Komatsu proposed a nitrene-radical mechanism based on the fact that the reaction shut down in the presence of oxygen. They designed a model reaction using 1,6-dienes, and as they expected, bicyclic pyrrolidines were isolated as products instead of aziridines. The role of silver in this reaction is not clear and most likely a free nitrene radical is released with the precipitation of silver(I) chloride (Fig. 18). 

Silver Nitrate, AgNOs. — Dissolve 50 gm. of the commercial crystals in 1000 cc. of distilled water. Let the solution stand a day, and if not clear, filter through glass wool, or better, siphon off the clear supernatant liquid. This solution should be kept free from dust and organic matter. 

Recently, novel nanomaterials have become a new frontier for SERS experiments, where different metals are collected together to form, for example, bimetallic particles. Thus, the same nanoparticle could be responsible for both SERS effect and catalytic activity. This is the case of the Ag/Pd colloids synthesized by chemical reduction with sodium borohydride (NaBH4) of silver nitrate (AgNOs) and palladium nitrate (Pd(N03)2), with a 96 4 Ag/Pd molar ratio [11]. The silver nanoparticles provide the SERS enhancement for the ligand molecules, while palladium may induce catalytic reactions. Also, in this case, TEM microscopy provides an important help to characterize these composite materials. In Fig. 20.6 TEM images at different magnifications are reported for bimetallic Ag/Pd particles, in comparison with those constituted by pure silver. While these latter present spheroidal shapes, bimetallic particles show more irregularities, due to palladium clusters in contact with the silver core surface.

The SI recommendation, supported by the International Union of Pure and Applied Chemistry and other international scientific bodies, is to abandon the use of the word "equivalent, and to refer to moles instead. However, the concept of the equivalent is still employed, even though the name has been dropped. Suppose, for example, that we pass one ampere of electricity for one hour through a dilute sulfuric acid solution and through solutions of silver nitrate, AgNOs, and cupric sulfate, CUSO4. The weights liberated at the respective cathodes are ...
