Barium nitrate is the inorganic compound with the chemical formula Ba(NO 3) 2. It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. [4]
Barium chloride is an inorganic compound with the formula Ba Cl 2. It is one of the most common water-soluble salts of barium . Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame.
Nitrate chlorides are mixed anion compounds that contain both nitrate (NO 3 −) and chloride (Cl −) ions. Various compounds are known, including amino acid salts, [ 1 ] and also complexes from iron group , rare-earth , and actinide metals.
A common nitrate test, known as the brown ring test [2] can be performed by adding iron(II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [3]
The group is determined by making a solution of the salt in water and adding ammonium chloride and ammonium hydroxide. Ammonium chloride is added to ensure low concentration of hydroxide ions. The formation of a reddish-brown precipitate indicates Fe 3+; a gelatinous white precipitate indicates Al 3+; and a green precipitate indicates Cr 3+ or ...
In analytical chemistry, argentometry is a type of titration involving the silver(I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration. Chloride ions react with silver(I) ions to give the insoluble silver chloride:
Barium chlorate, Ba(ClO 3) 2, is the barium salt of chloric acid. It is a white crystalline solid , and like all soluble barium compounds, irritant and toxic. It is sometimes used in pyrotechnics to produce a green colour .
Radium nitrate is a radioactive salt with the formula Ra(NO 3) 2. It is a white solid, but old samples appear yellowish-grey. Although radium chloride and radium bromide are less soluble than the corresponding barium salts, radium nitrate is more soluble than barium nitrate. [1] [2] It decomposes at 280 °C to radium oxide.
