The solution, which contains the nickel free from other metals, is heated, and a solution of sodic hydrate added in slight excess.
sodic nitrate, if used upon soil late in the season, may overcome a difficulty that has been recently noticed.
As sodic acetate and acetic acid did not interfere, it became desirable to make some experiments on the finishing point.
sodic nitrate subcutaneously applied to frogs kills them, in doses of ·026 grm.
That is to say, the stoneware becomes coated with a thin layer or glaze of sodic silicate or soda-glass.
It is prepared by dropping a strong solution of antimony trichloride into a saturated solution of sodic phosphate.
In presence of potassic or sodic chlorate, the blue colour immediately vanishes.
It is now cooled, some hydrochloric acid again added, and the mixture neutralised with sodic carbonate.
The addition of sodic bicarbonate prevents the otherwise inevitable reduction of the silver salt.
sodic phosphate gives a crystalline precipitate of solanine phosphate, if added to a solution of solanine sulphate.
