sulphocyanate

In these experiments 100 c.c. of "sulphocyanate" (very accurately measured) was run into the solution containing the weighed portion of bullion (fine silver) and, after shaking the solution, was filtered.

In the filtrate the remaining silver, if there should be any, was determined by the ordinary titration, but with "sulphocyanate" of one-tenth the strength.

After washing the print is immersed in a solution containing 0.5 parts of chloride of gold for 2,000 parts of distilled water, and then fixed in a bath of sulphocyanate of potassium, which tones the image blue-black.

The presence of this dangerous impurity is easily detected by adding ferric chloride, which, in presence of the sulphocyanate, produces a blood-red colour.

After this action has commenced, if the proof be not immediately immersed in a solution of sulphocyanate of potassium, Cu2Cl passes over to a higher combination of chlorine, and the paper is again fit to be impressed anew by the action of light.

As long as FeCl or even Cu2Cl is present, if the print is immersed in the sulphocyanate solution, sulphocyanate of copper is immediately formed on the reduced parts, while on the others the sulphocyanide of copper, formed and dissolved by the sulphocyanide of potassium in excess, becomes decom ‐ posed with water in soluble sulphocyanide of copper and deposited as such on the parts already covered with the salt.

Certain samples contain small quantities of ammonium sulphocyanate, an extremely poisonous substance for plants.

Those from the grained negatives employed in photogravure are still more perfectly developed in a tepid solution of potassium sulphocyanate, since the impressions wholly consist of insoluble parts (the lines) and gelatine not acted on.

_Sinapine_, the alkaloid which exists as sulphocyanate in white mustard seed, yields, under the same reaction as that applied to atropine and piperine, quite different results.

The solution of ammonium sulphocyanate should be compounded with auric chloride to tone the picture at the same time it is fixed; thus:
