Silver “hydroxide

Addition of an alkali hydroxide to a solution of a silver(I) salt gives a brown solid, silver(I) oxide, AgjO when wet, this behaves as silver hydroxide AgOH, for example... 

Hantzsch prepared this betaine by treating nicotinic acid methiodide with silver hydroxide and. lahns subsequently identified trigonelline with Hantzsch s synthetic base. 

In this method, sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, or sodium aluminate can be fed to the spent fixer for precipitation of silver ions as insoluble silver hydroxide precipitates. Figure 7 indicates that the residual silver concentration in the hydroxide precipitation treated effluent can be about 1 mg/L at pH 12 [19]. 

The brown precipitate was identified as silver hydroxide. Therefore B must be NaOH. 1 point for correctly identifying flask B as containing NaOH. 

Silver chlorate forms the triammine, [Ag(NH3)3]C103 silver carbonate the tetramminc, [Ag(NH3)2]2CO 3 and silver oxide itself forms diammino-silver oxide, Ag20.2NH3> and the hydroxide, [Ag(NIi3)2]OII.5 Diammino-silver hydroxide appears to be more strongly dissociated than barium hydroxide.6... 

Silver Nitrate. Dissolve several silver nitrate crystals in water and determine the pH of the solution. Does silver nitrate hydrolyze Is silver hydroxide a strong or a weak base What products are obtained in the thermal decomposition of silver nitrate Write the equation of the reaction. 

Tertiary amines do not react with nitrous acid, acetyl chloride, benzoyl chloride, benzenesulfonyl chloride, but react with alkyl halides to form quaternary ammonium halides, which are converted by silver hydroxide to quaternary ammonium hydroxides. Quaternary ammonium hydroxides upon heating yield (1) tertiary amine pins alcohol (or, for higher members, olefin plus water). Tertiary amines may also be formed (2) by alkylation of secondary amines, e.g., by dimethyl sulfate, (3) from amino acids by living organisms, e g, decomposition of fish in the case of trimethylamine. 

Dimethyl tellurium dihydroxide,2 (CH3)2Te(OH)2, is prepared by the action of silver hydroxide on the foregoing iodide, either by boiling the components in water or grinding them together with a little water in a mortar. The base forms a strongly alkaline solution which yields salts on treatment with halogen acids. 

Diphenyl benzyl tellurium bromide,1 (CeH5)2(C6H5.CH2)TeBr, from diphenyl telluride dissolved in benzyl bromide, forms a crystalline mass, M.pt. 90° to 91° C., converted by silver hydroxide into the corresponding hydroxide, a yellow oil, very soluble in water, and yielding a sparingly soluble picrate on treatment with picric acid. 

Aq. ammonia dissolves many of the heavy metal hydroxides—e.g. zinc, cadmium, cobalt, nickel, copper, and silver hydroxides chromic hydroxide dissolves in this... 

Silver hydroxide is used in exhaustive methylation, a process often utilised in order to obtain an unsaturated cyclic hydrocarbon from an amine by treating it with methyl iodide aud silver hydroxide the triniethyl-ammonium hydroxide obtained is then decomposed by distillation. 

Ammonia solution is then added gradually till the precipitated silver hydroxide just dissolves. A quantity of this solution, sufficient to oxidise the acrolein taken, is warmed to 60°—70° on the water-bath, and These quantities should not be departed from and the solution should not be allowed to evaporate, otherwise silver fulminate may be formed and a dangerous explosion may result. 

Silver oxide, Ao. O, is obtained as a dark-brown precipitate on the addition of sodium hydroxide to a solution of silver nitrate. It is slightly soluble, prodiuing a weakly alkaline solution of silver hydroxide ... 

Reacting with water, (H—OH), potassium hydroxide, K—OH, or silver hydroxide, Ag—OH, the radical will become united to the hydroxyl group, (OH). 

This synthesis of alcohols from alkyl halides takes place much better if instead of water we use another hydroxide, viz., silver hydroxide, AgOH, (moist silver oxide, Ag20 + H2O) which forms an insoluble silver salt with the halogen, the reaction thus proceeding in only one direction. 

This method, of course, always yields the alcohol corresponding to the hydrocarbon which is the mother substance of the alkyl radical of the halide used. The alcohol will contain the same number of carbon atoms as the alkyl halide, and it will possess the same structure. The reaction is accomplished in the first case with water by heating the halide with much water at ioo°-200°, the excess water preventing the reversion of the reaction, or by heating with water in the presence of alkalies to neutralize the acid formed. With silver hydroxide the reaction takes place at ordinary temperatures and is non-reversible. Lead hydroxide may also be used. As was stated under the alkyl halides the alkyl iodide is the halide most used because it is the most active.
