Barium is often used in barium-nickel alloys for spark-plug electrodes and in vacuum tubes as a drying and oxygen-removing agent.
Barium reacts with almost all of the nonmetals; all of its water-soluble and acid-soluble compounds are poisonous.
Barium carbonate is used in glass, as a pottery glaze, and as a rat poison.

Barium nitrate, Ba(NO3)2, is prepared by dissolving either the carbonate or sulphide in dilute nitric acid, or by mixing hot saturated solutions of barium chloride and sodium nitrate.
Barium carbonate, BaCOI, occurs rather widely distributed as witherite (q.v.), and may be prepared by the addition of barium chloride to a hot solution of ammonium carbonate, when it is precipitated as a dense white powder of specific gravity 4~3; almost insoluble in water.
Barium and its salts can be readily detected by the yellowishgreen color they give when moistened with hydrochloric acid and heated in the Bunsenflame, or by observation of their spectra, when two characteristic green lines are seen.

Barium production is stated at 6 million tons per year, strontium at 137,000 tons, cesium at 20 tons and rubidium in such low levels as to not be available.
A sample of the electrolysis compound, identified as barium sulphate, is subjected to a flame test using a nichrome wire.
For comparison purposes, the spectrum of barium chloride and barium hydroxide test salts in solution appears and measures identically within the green portion of the spectrum.

The simplest case is that of water and a salt, such as sodium chloride, which crystallizes without water.
It is not the heat effect when solid is dissolved in a large excess of solvent, and may differ so much from that effect as to have an opposite sign.
Thus cupric chloride dissolves in much water with an evolution of heat, but when the solution is nearly saturated, it is cooled by taking up more of the solid.
