Deliquescence Effervescence

The compound of this gas and ammonia was a perfect neutral salt, neither chan g the colour of turmeric or litmus it had no perceptible odotu, but a pungent saline taste it was deliquescent, and of course very soluble in water it was decomposed by the sulphuric, nitric, and phosphoric acids, and also by liquid muriatic acid but it sublimed unaltered in the muriatic, carbonic, and sulphureous acid gasses, and dissolved without effervescing in acetic acid. The products of its decomposition collected over mercury were found to be the carbonic and muriatic acid gasses and in the experiment with concentrated sulphuric acid Mien accurate results could be obtained, these two gasses were in such proportions, that the volume of the latter was double that of the former. 

Silver oxide transforms an aqueous solution of the hydrochloride to tnethylphosphohetaine (II). Concentration of the solution then melds very deliquescent crystals, which lose water after keeping for several months m vacuo over sulphuric acid, ghdiig the anhydtide (III). When an aqueous solution of the free base is concentrated by boiling, a solid mass remains which has a faint acid reaction and effervesces with acids it appears to be tnethylmethylphosphonmm acid carbonate, a compound isomeric vdth the base itself ... 

Characters and Tests.—Hard white pencils, very deliquescent, powerfully alkaline, and corrosive. A watery solution acidulated by nitric acid gives a yellow precipitate (potassium-platinic chloride) with platinic chloride, indicating the presence of potassium. It should dissolve in diluted nitric acid without effervescence, showing the absence of carbonate, and give but scanty white precipitates with barium chloride and silver nitrate, showing the presence of traces only of sulphate and chloride respectively. 

Characters and Tests.—Colourless right rhombic prisms, not deliquescent saline, feebly alkaline taste not corrosive. The addition of diluted hydrochloric acid causes strong effervescence (escape of carbonic anhydride), and forms a solution which gives a yellow precipitate (potassium-platinic chloride) with platinic chloride. An aqueous solution gives...
