Nitrates, Chlorides, and Carbon Dioxide. — On heating 100 gin. of copper oxide, and passing over it a stream of moist air freed from carbonic acid, no vapors should be given off which redden litmus paper, or render lime water turbid. 

Calcium Pyroarsenite, Ca2As205, is a white powder obtained by slowly precipitating a solution of arsenious acid with excess of lime-water, or by adding calcium chloride or sulphate to aqueous ammonium arsenite, and heating the precipitate to 105° C.7 If the product is dried in the air at the ordinary temperature, the monohydrate is obtained. At red heat calcium arsenate is formed. The pyroarsenite is only slightly soluble in water, 100 parts dissolving 0-025 to 0-030 part of the salt. It is more soluble in the presence of alkali chlorides and some ammonium salts, such as the nitrate, sulphate, acetate and succinate.8 It also dissolves in dilute acids. 

Fulminating silver was prepared in 1788 by Berthollet who precipitated a solution of nitrate of silver by means of lime water, dried the precipitated silver oxide, treated it with strong ammonia water which converted it into a black powder, decanted the liquid, and left the powder to dry in the open air. Fulminating silver is more sensitive to shock and friction than fulminating gold. It explodes when touched it must not be enclosed in a bottle or transferred from place to place, but must be left in the vessel, or better upon the paper, where it was allowed to dry. 

Carbon will glow and bum away almost completely a light-coloured ash may remain. If the black substance is dropped in very small quantities into a little fused potassium nitrate contained in a hard glass tube, the oxidation will be more vigorous and some potassium carbonate will be formed. The residue will evolve carbon dioxide on treatment with dilute acids. Additional confirmation of carbon is obtained by heating an intimate mixture of the substance with dry copper(II) oxide in a hard glass tube carbon dioxide will be evolved (test with lime water), and red metallic copper will remain. 

PrecipUaHon processes are only adapted to hard waters, and are de s ed to separate the excess of calcium salt, and at the same time a considerable quantity of organic matter, which is mechanically carried down with the preeijiitate. e method usually followed consists in the addition of lime (in the form of lime-water), in just Bofi cieut ontity to neutralize the excess of carbon dioxide present w the water, llie added lime, together with the calcium salt naturally present in the -water, is then precipitated, except that small portion of calcium carbonate which the water, freed from carbon dioxide, is capable of dissolving. To determine when sufficient lime-water has been added, take a sample from time to time during the addition, and test it with solution of silver nitrate until a brown precipitate is formed. At this point cease the addition of lime-water and mix the limed water with further portions of the haid water, until a sample, treated with silver-nitrate solution, gives a yellowish in place of a brown color.

Tests.— A fluid ounce evaporated in a clean glass capsule should leave scarcely any visible residue, indicating the. absence of solid non-volatile impurities. Should not be affected by sulphuretted hydrogen, ammonium oxalate, silver nitrate, barium chloride, or lime water, proving the absence of lead and other metals precipitable by sulphuretted hydogen, calcium salts, chlorides, sulphates, carbonates, and carbonic acid respectively. 

Incompatibles —Acids fixed alkalies and their carbonates lime-water nitrate of silver acetate of lead and metallic sulphates. 

When diluted with four times its volume of distilled water, it should give no precipitate with lime-water, showing the absence of ammonium carbonate no precipitate with ammonium oxalate, indicating the absence of calcium no precipitate with ammonium sulphide, showing the absence of iron and no precipitate with copper ammonio-sulphate, proving the absence of ammonium sulphide. Liquor Ammonias fortior acidified with nitric acid should not be rendered turbid by silver nitrate, indicating the absence of chlorine, or by barium chloride, showing that it is free from sulphate. 

Incompatibles.— Alkalies and their carbonates lime-water acetate of lead nitrate of silver astringent vegetable infusions and milk.
