Strontium nitrate Strontium nitrate Strontium nitrate is an inorganic compound made of the elements strontium and nitrogen with the formula Sr(NO). This colorless solid is used as a red colorant and oxidizer in pyrotechnics. Strontium nitrate is typically generated by the reaction of nitric acid on strontium carbonate. Like many other strontium salts, strontium nitrate is used to produce a rich red flame in fireworks and road flares. The oxidizing properties of this salt are advantageous in such applications. Strontium nitrate can aid in eliminating and lessening skin irritations. When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation
Cobalt(II) nitrate dihydrate is a two-dimensional polymer, with nitrate bridges between Co(II) centres and hydrogen bonding holding the layers together. The tetrahydrate consists of discrete, octahedral [(HO)Co(NO)] molecules. The hexahydrate is better described as hexaaquacobalt(II) nitrate, [Co(OH)][NO], as it consists of discrete [Co(OH)] and [NO] ions. Above 55 °C, the hexahydrate converts to the trihydrate and at higher temperatures to the monohydrate. It is commonly reduced to metallic high purity cobalt. It can be absorbed on to various catalyst supports for use in Fischer-Tropsch catalysis. It is used in the preparation of dyes and inks. The hexahydrate is prepared treating metallic cobalt
