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
Lead(II) nitrate has a standard reduction potential (E) of −0.125 V, or the nitrate ion, which under acidic conditions has an E of +0.956 V. The nitrate would function at high temperatures or in an acidic condition, while the lead(II) works best in a neutral aqueous solution. When heated, lead(II) nitrate crystals decompose to lead(II) oxide, oxygen and nitrogen dioxide. Because of this property, lead nitrate is sometimes used in pyrotechnics such as fireworks. Lead(II) nitrate is soluble in water but is almost insoluble in nitric acid. Because of the hazardous nature of lead(II) nitrate, there is a preference for using alternatives
