Sodium peroxodisulphate

Ammonium peroxodisulphate detonates when it is heated above 75°C, but there is the same result at ambient temperature in the presence of water, carbon dioxide or sodium peroxide. [Pg.186]

IV.25 PEROXODISULPHATES. S20 Solubility The best known per-oxodisulphates, those of sodium, potassium, ammonium, and barium are soluble in water, the potassium salt being the least soluble, (17 7 g 1 at 0°C). [Pg.349]

Sodium bismuthate This reagent, in the presence of dilute nitric acid, converts cerium(III) ions into cerium(IV) in the cold. A similar result is obtained by heating with ammonium peroxodisulphate or with lead dioxide and dilute nitric acid (1 2). In all cases, the solutions become yellow or orange in colour. [Pg.541]

The rate coefficient 2 is proportional to the concentration of phenolate ion thus for 2-hydroxy-pyridine (pA A = 11-6) oxidation below pH 8 is slower than the spontaneous decomposition of peroxodisulphate. For the reaction of 2-hydroxy-P5rridine in 2 M sodium hydroxide, the variation of 2 with temperature is expressed by... [Pg.477]

Disodium peroxodisulphate EINECS 231-892-1 Peroxy-disulfuric acid, disodium sail Persulfate de sodium Sodium peroxydisulfate Sodium persulfate UN1505. Bleaching agent (fats, oils, fabrics, soaps), battery depolarizers, emulsion polymerization. Soluble In H2O (549 g/l MLD (rbt iv) = 178 mg/kg. Degussa AG FMC Corp. ... [Pg.572]

Next treat the hydrochloric solution containing the nickel with 3 ml of diacetyl dioxime solution, 1 ml of 10 m sodium hydroxide solution and 0.3 ml of ammonium peroxodisulphate solution, mixing well each time. Dilute with water to the mark at 20 C, leave to stand for about 2 hours, and measure in a 3-cm cuvette at 60 nm against distilled water. Carry out a blank test concurrently and take into account accordingly. [Pg.383]
