Silver carbonate , solubility

Write a balanced dissolution equation and solubility product expression for silver carbonate, Ag2C03. 

A chemist finds that the solubility of silver carbonate, Ag2C03, is 1.3 X 10 mol/L at 25°C. Calculate Ksp for silver carbonate. 

A much more systematic approach involves the use of p-chlorides carrying non-participating groups at C-2 as is exemplified by the Wolfrom synthesis of p-isomaltose octa-acetate from 1,2,3,4-tetra-O-acetyl-p-D-glucopyranose and 3,4,6-tri-0-acetyl-2-0-nitro-p-D-glucopyranosyl chloride In this work silver carbonate was used as acid acceptor and soluble silver perchlorate was fmmd to exert valuable catalytic influence, but later the perchlorate itself was used in an application to a tiisacchar-ide s mthesis which incorporated the trityl ether modification 2 ).

Chloro-pentammino-chromic Sulphate, [Cr(N I3)5Cl]S04.2H20, is prepared by treating the chloride with silver carbonate, removing the precipitated silver chloride and cautiously adding to the liquid dilute sulphuric acid a little silver chloride is thereby precipitated, it is removed by filtration, and the sulphate is precipitated from the filtrate by means of alcohol in carmine-red prisms. It is fairly soluble in water, and loses water if left over sulphuric acid or on heating to 100° C. 

In their synthesis of convallatoxin, Reichstein and coworkers16 made some minor modifications in the Meystre-Miescher procedure. Because of the low solubility of strophanthidin (2) in benzene, the anhydrous aglycon was dissolved in a small volume of absolute p-dioxitne. Pure, dry silver carbonate was introduced and, under efficient stirring, a solution of the halide in benzene was added over a period of three hours, while distillation was maintained at a rate equal to that of the addition, thus keeping the volume of the solution in the flask at a constant (and small) volume. After addition of the halide was complete, a small volume of absolute benzene was added dropwise over a period of one hour, with distillation maintained as in the foregoing. By this procedure, the yield of tri-O-acetylcopvalla-toxin amounted to 44%.

Aliphatic nitroso compounds can be prepared from IV-alkylhydioxylamines oxidation widi bromine, chlorine or sodium hypochlorite in weakly acidic solution, reaction with potassium dichromate in acetic or sulfuric acid, and by oxidation widi yellow mercury(II) oxide in suspension in an organic solvent. Silver carbonate on Celite has also been used to prepare aliphatic nitroso compounds, such as ni-trosocyclohexane, in high yield from the corresponding hydroxylamines." Aqueous sodium periodate and tetraalkylanunonium periodates, which are soluble in organic solvents, are the reagents most commonly used for the oxidation of hydroxamic acids and IV-acylhydroxylamines to acylnitroso compounds... 

Phenylmercuric carbonate is prepared from the chloride in a similar manner to the nitrate using silver carbonate. It forms small, white needles, very slightly soluble in boiling water, easily soluble in boiling alcohol or benzene. When heated it melts with decomposition, and with strong acids gives carbon dioxide and the corresponding salts. 

The silver-carbon bond in compounds containing a perfluoroalkyl group is considerably more stable than in non-fluorinated compounds. The synthesis can be accomplished by the nucleophilic addition of silver fluoride to fluoro-olefines. A typical example of this reaction is given in equation 9. The complexes are soluble in organic solvents and have been isolated as the 1 1 complexes with acetonitrile [RAg(CH3CN)]23. 

Silver chloride has a larger K p than silver carbonate (see Table 16.2). Does this mean that AgCl also has a larger molar solubility than Ag2C03 ...

T. Christensen prepared chromic nitritopcntamminocarbonate, [Cr(NH3)5-(N02)]C03, by triturating an excess of silver carbonate with the chloride of the series, and treating the filtrate with alcohol. The yellow, crystalline product could not be obtained pure. It is easily decomposed is freely soluble in water and the soln. gives the characteristic reactions of the carbonates. 

First we find the molar solubility and then convert moles to grams. The solubility equilibrium for silver carbonate is ... 

Richtmyer and Hudson obtained a new heptaacetate of celtrobiose in 5% yield, by treating crystalline acetylceltrobiosyl chloride with silver carbonate in aqueous acetone. Since it was very sparingly soluble in ether it was separated from the more soluble normal heptaacetates by extraction in a Soxhlet apparatus. It melted (216°) at a considerably higher temperature than the other heptaacetates and, unlike the a- and... 

Example 2.10 The solubility product of the silver carbonate Ag COj in water at 25 °C is equal to 6.24-10" I It is necessary to determine solubility of this salt under the same conditions.
