  • It may be prepared in the amorphous form by heating cobalt with sulphur dioxide, in a sealed tube, at 200° C. In the hydrated condition it is formed by the action of alkaline sulphides on cobaltous salts, or by precipitating cobalt acetate with sulphuretted hydrogen (in the absence of free acetic acid).

  • Hydrocobaltocyanic acid is not known, but its potassium salt, K4Co(CN) 6, is formed when freshly precipitated cobalt cyanide is dissolved in an ice-cold solution of potassium cyanide.

  • In alkaline solution it readily takes up oxygen and is converted into potassium cobalticyanide, K 3 Co(CN) 6, which may also be obtained by evaporating a solution of cobalt cyanide, in excess of potassium cyanide, in the presence of air, 8KCN+2Co(CN)2+H20+0= 2K 3 Co(CN) 6 +2KHO.

  • The aqueous solution, however, does not show the ordinary reactions of cobalt or of ammonia, and so it is to be presumed that the salt ionizes into [Co(NH 3) 6] and 3C1'.

  • Sodium gives an intense and persistent yellow flame; lithium gives a carmine coloration, and may be identified in the presence of sodium by viewing through a cobalt glass or indigo prism; from potassium it may be distinguished by its redder colour; barium gives a yellowishgreen flame, which appears bluish-green when viewed through green glass; strontium gives a crimson flame which appears purple or rose when viewed through blue glass; calcium gives an orange-red colour which appears finch-green through green glass; indium gives a characteristic bluish-violet flame; copper gives an intense emerald-green coloration.

  • For soft iron, tungsten-steel and nickel little difference appeared to result from lowering the temperature down to - 186° C. (the temperature of liquid air); at sufficiently high temperatures, 600 to 1000° or more, it was remarked that the changes of length in iron, steel and cobalt tended in every case to become proportional to the magnetic force, the curves being nearly straight lines entirely above the axis.

  • The behaviour of cobalt is particularly noticeable; its permeability increased with rising temperature up to a maximum at 500°, when it was about twice as great as at ordinary temperatures, while at 1600°, corresponding to white heat, there was still some magnetization remaining.

  • As regards the higher temperatures, the chief point of interest is the observation that the curve of magnetization for annealed cobalt shows a small depression at about 450°, the temperature at which they had found the sign of the length-change to be reversed for all fields.

  • In the better explored parts along the great lakes and the railways, ores of gold, silver, nickel, cobalt, antimony, arsenic, bismuth and molybdenum have been obtained, and several important mines have been opened up. Gold has been found at many points across the whole province, from the mines of the Lakeof-the-Woods on the west to the discoveries at Larder Lake on the east; but in most cases the returns have been unsatisfactory, and only a few of the gold mines are working.
