Strontium chlorate chloride

The chemistry that governs barium salts, as used in green stars, is somewhat analogous to that of the strontium salts employed in red stars since both elements are found in the same group of the periodic table. While the use of compounds such as strontium chloride, strontium chlorate or strontium perchlorate might be considered to be appropriate... 

When our family gets to the park, they find themselves a place on the lawn, which was fertilized with a mixture of ionic compounds, including iron(II) sulfate. They eat their dinner and play in the park until it s time for the fireworks. The safety matches used to light the rockets contain barium chromate, and ionic compounds in the fireworks provide the colors red from strontium chlorate, white from magnesium nitrate, and blue from copper(II) chloride. 

Other inorganic crystals studied by Mark and his collaborators, sometimes leading to complete structure determinations, include strontium chloride, zinc hydroxide, tin tetraiodide, potassium chlorate, potassium permanganage, and ammonium ferrocyanide. Minerals investigated by them include CaSO (anhydrite), BaSO (barite), PbSO, Fe2TiO[j (pseudobrookite), and three forms of Al2Si05 (cyanite, andalusite, and sillimanite). 

In 1815, L. G. Gilbert1 noticed that thoroughly dried calcium oxide or hydroxide does not react chemically with dry chlorine, and similarly, in 1879, J. K. Weisherg showed that the same remark applies to dry barium or strontium oxide. The case is very different if moisture he present. With barium hydroxide two gram-atoms of chlorine are absorbed per gram-atom of the bivalent barium, and barium chloride and chlorate are produced so that if barium hypochlorite is formed as the first product of the reaction, it is immediately decomposed 3Ba(0Cl)2=Ba(C103)2 +2BaCl2 with calcium and strontium hydroxides, the reaction appears to he much... 

P. Grouvelle (1821)10 observed that a mol. of barium hydroxide absorbs two gram-atoms of chlorine, forming a product from which all the chlorine is expelled by carbon dioxide in two days. A. J. Balard (1834) says that the direct combination of hypochlorous acid with the powerful bases is accompanied by the development of much heat, and if the temp, is allowed to rise, the hypochlorite which may be formed changes into chlorate and chloride. By neutralizing a well-cooled soln. of the base with hypochlorous acid, A. J. Balard prepared soln. of calcium, strontium, and barium hypochlorites, the existence of which, he said, is incontestable and added that calcium and barium hypochlorites serve for the preparation of other hypo-...

A solution of chlorate of strontium makes tho flash a bright crimson. Chlorate of barium, green. Nitrate of potassium, violet. Chlorate of copper, bluo. Any ono of tho foregoing chlorates may bo prepared by mixing a warm solution of tho corresponding chloride with an equivalent quantity of a warm solution of chlorate of potossa the precipitate formed will be chlorido of potassium, and tho clear liquid, poured off, will be the desired chlorate, to be used for saturating the gun-paper.

Potassium chlorate or sodium chloride reacts rather actively on magnesium potassium perchlorate less actively than the above potascium nitrate very slowly and at room temperature it looks as if no reaction occurs at all barium nitrate, strontium nitrate or potassium bichromate cause no reaction.

These comprise, on the one hand, easily combustible substances such as charcoal, sulphur, antimony sulphide, resins, and tar and on the other hand, they include substances which readily give up oxygen and support combustion, such as saltpetre (potassium nitrate), and potassium chlorate or other chlorates. A third category includes those substances used for the various colour effects (barium strontium, copper, and other salts), and also finely divided metals, and coarse particles of charcoal to cause sparks and showers of fire ( golden rain and the like). Other substances are sometimes used to decrease the rate of burning and to increase brilliance (r.g. mercurous chloride and mercuric thiocyanate).

The simultaneous detection of small cations (ammonium, sodium, potassium, calcium, magnesium, and strontium) and anions (bromide, chloride, nitrite, nitrate, sulfate, perchlorate, thiocyanate, and chlorate) from low explosives in postblast residue using an elaborate electrolyte composed of a cationic chromophore and modifiers (imidazole/HIB A/18-crown-6 ether/ACN), an anionic chromophore (1,3,6-naphthalenesulfonic acid) and flow reversal agent (tetramethylammonium hydroxide) has been presented.
