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
Rubidium nitrate for manufacture of catalysts and in scintillation counters. It is rarely used in fireworks to produce a red-violet colour. RbNO can be prepared either by dissolving rubidium metal, its hydroxide or carbonate in nitric acid. Rubidium nitrate Rubidium nitrate is an inorganic compound with the formula RbNO. This alkali metal nitrate salt is white and highly soluble in water. Rubidium nitrate is a white crystalline powder that is highly soluble in water and very slightly soluble in acetone. In a flame test, RbNO gives a mauve/light purple colour. Rubidium compounds have very few applications. Like caesium nitrate, it is used
