Zinc is a bluish-white metal, malleable and ductile at 150°C, but at 180°C it changes rapidly so that at 205°C it may be easily powdered remains lustrous in dry air but is slightly tarnished in moist air or in water burns upon heating to vaporization with a bluish flame, forming zinc oxide soluble in acids—slowly when pure but rapidly on contact with copper or platinum soluble in alkalies. Discovery prehistoric. [Pg.1774]

Tin(II) chloride solution red or yellow colouration, due to colloidal platinum, soluble in ethyl acetate or in ether. [Pg.517]

Properties Greenish-gray powder that forms double salts with the chlorides of the alkali metals. D 5.87, mp decomposes at red heat, yielding platinum. Soluble in hydrochloric acid and ammonium hydroxide insoluble in water. [Pg.1002]

Properties Grayish-black, porous mass of finely divided platinum. Soluble in aqua regia. [Pg.1002]

Platinum—soluble salts (sodium chloroplatinate ammonium chloroplatinate, platinum tetrachloride) Sensitizers causing asthma and dermatitis. Metallic platinum does not share these effects. Soluble platinum compounds are also highly irritating to eyes, mucous membranes, and respiratory tract. 0.002 mg/m (as Pt) 4mg/m (as Pt) Appearance varies with the compound. Thermal-breakdown products of some chloride salts Include chlorine gas. Used as Industrial catalysts and In specialized photographic applications. [Pg.606]

The solubility of platinum in phosphoric acid was measured at 176 and 196 °C and was found to be consistent with the Nemst equation (Bindra et al. 1979). However, recent measurements of platinum solubility in 0.5 M sulfuric acid at 80 °C (Ferreira et al. 2005) and in 0.57 M perchloric acid at 23 °C do not follow the Nemst equation (Wang et al. 2006). [Pg.364]

Line H is a line of constant platinum solubility based on the Nemst equation assuming that standard potential does not change with temperature ... [Pg.372]
