Description and uses: a water soluble barium compound.
In a hot flame (bunsen or alcohol) it colours the flame a bright green.
As a nitrate, it's a powerful oxidiser on a par with potassium nitrate (saltpetre) and used therefore in pyrotechnics for its bright green flame.
In analytical chemistry it is used for the quantitative gravimetric determination of sulphur-bearing compounds, after oxidation to sulphate and precipitation as BaSO4.
