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
Iron(III) nitrate reagent called "Clayfen"—has been employed for the oxidation of alcohols to aldehydes and thiols to disulfides. Ferric nitrate solutions are used by jewelers and metalsmiths to etch silver and silver alloys. Iron(III) nitrate Iron(III) nitrate, or ferric nitrate, is the chemical compound with the formula Fe(NO). Since it is deliquescent, it is commonly found in its nonahydrate form Fe(NO)·9HO in which it forms colourless to pale violet crystals. When dissolved, it forms yellow solution due to hydrolysis. The compound is prepared by treating iron metal powder with nitric acid. Ferric nitrate is the catalyst of choice for the synthesis of
