Acid variety

Usage examples of nitric.

If acetic acid is used instead of nitric in the first instance this addition of water is unnecessary.

The bismuth is precipitated by the addition of ammonic carbonate, and the solution, after filtering and acidifying with nitric acid, is re-electrolysed.

Zinc is detected by dissolving the substance in hydrochloric or nitric acid, boiling, and adding sodic hydrate in excess, filtering, and adding ammonic sulphide to the filtrate.

When the alkaloid is heated in a watchglass with a drop of strong sulphuric acid until the acid begins to fume, and is then allowed to get quite cold, a drop of nitric acid produces a brilliant red colour.

Sulphites are of little importance to the assayer, and are converted into sulphates by the action of nitric acid and other oxidising agents.

In addition to the nitric acid and glycerin Yousef mixed into nitro, he imported sodium azide, the primary explosive used to detonate airbags, along with mercury fulminate, another explosive.

I bad tested for morphine with nitric acid, permuriate of iron, chromate of potash, and, most important of all, iodic acid.

It unquestionably prevents the loss of considerable nitric acid from leaching during the winter and early spring.

Generally it answers the same purpose as aqua regia, and is employed where the addition of nitric acid to a solution has to be specially avoided.

In alloys it may be found by dissolving them in nitric acid or in aqua regia, evaporating with hydrochloric acid, and treating the filtrate with ammonic chloride and alcohol.

They are soluble in nitric acid or aqua regia, and, provided the solution is sufficiently acid, they remain dissolved.

Mercury, which if present would interfere, is separated because of the insolubility of its sulphide in nitric acid.

If nickel is present, the few milligrams of copper remaining in the electrolysed solution should be separated with sulphuretted hydrogen, the precipitated sulphide dissolved in nitric acid, and determined colorimetrically.

The nickel is separated from the solution by boiling with sodic hydrate, filtering, and dissolving the precipitate in nitric acid.

When much copper is present it is best separated in a nitric acid solution by electrolysis.
