Aluminium rubidium sulphate (I2H2O) [7784-29-4] M 496.2. Crystd from aq H2SO4 (ca 2.5ml/g). [Pg.362]

Rubidium chlorate, RbC10s.—The chlorate is obtained by the interaction of rubidium sulphate and barium chlorate. On heating, it decomposes like potassium chlorate. It is less soluble in water than the corresponding potassium salt, the solubility at 19° C. being 5-1 grams in 100 grams of water.12... [Pg.193]

Rubidium hydroxide, RbOH.—The hydroxide is formed by dissolving the metal in water, or by the action of barium hydroxide on rubidium sulphate. It is a very deliquescent substance, and is volatilized by heat. Its melting-point8 is 301° C., and its density9 3-203 at 11° C. The latent heat of fusion per mol. is 1-614 Cal.10 the heat of formation from the elements is 101-99 Cal.11 A monohydrate and a dihydrate have been described.12... [Pg.194]

Rubidium sulphate, Rb2S04.—The sulphate forms rhombic crystals isomorphous 2 with those of potassium sulphate, melting3 at 1074° C., the density at 20° C. being 3-6113, and at 60° C. 3-5943.4 It exists in two modifications,5 the transition-point being 657° C. The heat of formation from the elements is 344-68 Cal., and the heat of solution —6-66 Cal. at 15° C.6 The solubility 7 is given in the appended table ... [Pg.195]

Rubidium dithiouate, Rb2S206.—The dithionate is formed by the action of rubidium sulphate on barium dithionate.3... [Pg.196]

Rubidium nitrite, RbN02.—Barium nitrite and rubidium sulphate interact to form rubidium nitrite, a yellowish, crystalline substance, very soluble in water.2... [Pg.197]

The preparation of rubidium and caesinm carbonates.—Bunsen made rubidium carbonate by treating rubidium sulphate with barium hydroxide, and evaporating the filtrate to dryness with ammonium carbonate, when crystals of the carbonate separate. R. Bunsen also transformed rubidium chloride into carbonate by first heating the chloride with nitric acid to convert it into the nitrate, and then treating the latter with an excess of oxalic acid. The oxalate is converted to carbonate by calcination. H. L. Wells made csesium carbonate by L. Snoith s process, viz, by evaporating to dryness a mixture of csesium nitrate with twice as much oxalic acid, dissolved in a little water, and calcining the residue in a platinum crucible. Caesium carbonate forms a syrupy liquid which crystallizes with difficulty. [Pg.725]
