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
Ethyl nitrate Ethyl nitrate Ethyl nitrate is the ethyl ester of nitric acid and has the chemical formula . It is a colourless, volatile, highly flammable liquid. It is used in organic synthesis and as an intermediate in the preparation of some drugs, dyes, and perfumes. Ethyl nitrate is found in the atmosphere, where it can react with other gases to form smog. Originally thought to be a pollutant, formed mainly by the combustion of fossil fuels, recent analysis of ocean water samples reveal that in places where cool water rises from the deep, the water is saturated with alkyl nitrates, likely
