Strontium carbonate a mineral, strontium carbonate is prepared synthetically in one of two manners. First of which is from naturally occurring celestine also known as strontium sulfate (SrSO) or by using soluble strontium salts by the reaction in solution with a soluble carbonate salt (usually sodium or ammonium carbonates). For example if sodium carbonate was used in solution with strontium nitrate: Sr(NO) + NaCO → SrCO + 2 NaNO . The most common use is as an inexpensive colorant in fireworks. Strontium and its salts emit a brilliant red color in flame. Unlike other strontium salts, the carbonate salt is generally preferred
Lead(II) nitrate rotation of the nitrate groups within the crystal lattice at elevated temperatures, but this did not materialise. Lead(II) nitrate can be obtained by dissolving metallic lead in aqueous nitric acid: More commonly, it is obtained by dissolving lead(II) oxide in nitric acid: In either case, since the solvent is concentrated nitric acid (in which lead(II) nitrate has very low solubility) and the resulting solution contains nitrate ions, anhydrous crystals of lead(II) nitrate spontaneously form as a result of the common ion effect: Most commercially available lead(II) nitrate, as well as laboratory-scale material, is produced accordingly.
