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
Mercury(I) nitrate Mercury(I) nitrate Mercury(I) nitrate is a chemical compound with the formula Hg(NO). It is used in the preparation of other mercury(I) compounds, and is toxic. Mercury(I) nitrate is formed when elemental mercury is combined with "dilute" nitric acid (concentrated nitric acid will yield mercury(II) nitrate). Mercury(I) nitrate is a reducing agent which is oxidized upon contact with air. Mercuric nitrate can be reacted with elemental mercury to form mercurous nitrate. Solutions of mercury(I) nitrate are acidic due to slow reaction with water: Hg(NO)(OH) forms a yellow precipitate. If the solution is boiled or exposed to light, mercury(I) nitrate undergoes a
