Reactions
At elevated temperatures, barium nitrate decomposes to barium oxide, nitrogen dioxide, and oxygen:
- 2Ba(NO3)2 + heat → 2BaO + 4NO2 + O2
In an atmosphere of nitric oxide, thermal decomposition produces barium nitrite. Reactions with soluble metal sulfates or sulfuric acid yield barium sulfate. Many insoluble barium salts, such as the carbonate, oxalate and phosphate of the metal, are precipitated by similar double decomposition reactions. Barium nitrate is an oxidizer and reacts vigorously with common reducing agents. The solid powder, when mixed with many other metals such as aluminium or zinc in their finely divided form, or combined with alloys such as aluminium-magnesium, ignites and explodes on impact.

Famous quotes containing the word reactions:
“In this Journal, my pen is a delicate needle point, tracing out a graph of temperament so as to show its daily fluctuations: grave and gay, up and down, lamentation and revelry, self-love and self-disgust. You get here all my thoughts and opinions, always irresponsible and often contradictory or mutually exclusive, all my moods and vapours, all the varying reactions to environment of this jelly which is I.”
—W.N.P. Barbellion (1889–1919)
“Cuteness in children is totally an adult perspective. The children themselves are unaware that the quality exists, let alone its desirability, until the reactions of grownups inform them.”
—Leontine Young (20th century)
“Separation anxiety is normal part of development, but individual reactions are partly explained by experience, that is, by how frequently children have been left in the care of others.... A mother who is never apart from her young child may be saying to him or her subliminally: “You are only safe when I’m with you.””
—Cathy Rindner Tempelsman (20th century)
