Strontium nitrate is an inorganic compound composed of the elements strontium, nitrogen and oxygen with the formula Sr (NO 3) 2. This colorless solid is used as a red colorant and oxidizer in pyrotechnics.
Infobox references. Strontium nitride, Sr 3 N 2, is produced by burning strontium metal in air (resulting in a mixture with strontium oxide) or in nitrogen. Like other metal nitrides, it reacts with water to give strontium hydroxide and ammonia: Sr 3 N 2 + 6 H 2 O → 3 Sr (OH) 2 + 2 NH 3.
Because Sr(OH) 2 is slightly soluble in cold water, its preparation can be easily carried out by the addition of a strong base such as NaOH or KOH, drop by drop to a solution of any soluble strontium salt, most commonly Sr(NO 3) 2 (strontium nitrate). The Sr(OH) 2 will precipitate out as a fine white powder. From here, the solution is filtered ...
Sodium compounds glow yellow in a flame. A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction.
Strontium sulfide is the inorganic compound with the formula Sr S. It is a white solid. The compound is an intermediate in the conversion of strontium sulfate, the main strontium ore called celestite (or, more correctly, celestine), to other more useful compounds. [2][3][4]
Natural stable strontium, on the other hand, is not hazardous to health.'Strontium is a chemical element; it has symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air.
Cobalt nitrate is the inorganic compound with the formula Co (NO 3) 2. xH 2 O. It is cobalt (II)'s salt. The most common form is the hexahydrate Co (NO 3) 2 ·6H 2 O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents. [2]
