Nickel sulphates

CH3CH1CH2CH2OCH2CH2OH. Colourless liquid with a pleasant odour b.p. 17rC. Manufactured by heating ethylene oxide with 1-butanol in the presence of nickel sulphate as a catalyst. Used as a solvent in brushing lacquers. [Pg.168]

Skin Inorganic acids (chromic, nitric) organic acids (acetic, butyric) inorganic alkalis (sodium hydroxide, sodium carbonate) organic bases (amines) organic solvents. Dusts Detergents salts (nickel sulphate, zinc chloride) acids, alkalis, chromates. ... [Pg.68]

Soluble corrosion products may increase corrosion rates in two ways. Firstly, they may increase the conductivity of the electrolyte solution and thereby decrease internal resistance of the corrosion cells. Secondly, they may act hygroscopically to form solutions at humidities at and above that in equilibrium with the saturated solution (Table 2.7). The fogging of nickel in SO2-containing atmospheres, due to the formation of hygroscopic nickel sulphate, exemplifies this type of behaviour. However, whether the corrosion products are soluble or insoluble, protective or non-protective, the... [Pg.336]

Most nickel electroplating is carried out in solutions based oh the mixture of nickel sulphate, nickel chloride and boric acid proposed, by O. P., Watts . Typical composition and operating conditions are ... [Pg.524]

The Watts Solution, is a relatively cheap, simple solution which is easy to control and keep pure. The nigkel sulphate acts as the main source of nickel ions, though nickel chloride is an additional source. Higher deposition rates can be, used when the ratio of nickel chloride to nickel sulphate is raised and some proprietary bright nickel solutions are available in a high-speed version which contains an increased concentration of nickel chloride. [Pg.524]

Nickel sulphate (N1S04-7H20) 180g/1 Nickel chloride (NiClj-fiHjO) 30g/1 Ammonium chloride (NH4CI) 25 g/1 Boric acid (HjBOj) 30 g/1... [Pg.531]

Procedure. A. Nickel in a nickel salt. Weigh out accurately 0.3-0.4g of pure ammonium nickel sulphate (NH4)2S04-NiS04,6H20 into a 500mL beaker provided with a clockglass cover and stirring rod. Dissolve it in water, add 5 mL of dilute hydrochloric acid (1 1) and dilute to 200 mL. Heat to 70-80 °C,... [Pg.462]

Reagents. Standard nickel and cobalt ion solutions. Prepare solutions of nickel and cobalt ion (ca 10 mgmL"1) from pure ammonium nickel sulphate and pure ammonium cobalt sulphate respectively. [Pg.533]

Prepare the standard nickel solution by dissolving 0.673 g pure ammonium nickel sulphate in water and diluting to 1 L 1 mL contains 0.1 mg of Ni. The solution may be further diluted to a basis of 0.01 mg of Ni per mL, if necessary. Pure nickel may also be employed for the preparation of the standard solution. [Pg.694]

Detergents salts (nickel sulphate, zinc chloride) acids, alkalis, chromates. [Pg.34]

Biological Effects of Mercuric Chloride, Nickel Sulphate and Nickel Chloride... [Pg.189]

Mercuric chloride, nickel sulphate and nickel chloride are water-soluble salts. The present knowledge of these compounds regarding metabolism, chemical interactions and biological effects on different tissues will be reviewed. [Pg.190]

NICKEL SULPHATE (NiS04 -6H20) AND NICKEL CHLORIDE... [Pg.207]

The major contribution to ambient nickel originates from the combustion of fossil fuels one of the predominant forms in air is nickel sulphate [263]. In electroplating shops and electro-refining plants, workers are exposed to aerosols of dissolved nickel salts electroplating using nickel sulphate accounts for about 20% of the nickel produced [264]. [Pg.207]
