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
Ceric ammonium nitrate and 3,4-dimethoxybenzyl ethers, which are protecting groups for alcohols. Two equivalents of CAN are required for each equivalent of "para"-methoxybenzyl ether. The alcohol is released, and the "para"-methoxybenzyl ether converts to "para"-methoxybenzaldehyde. The balanced equation is as follows: CAN is also a component of chrome etchant, a material that is used in the production of photomasks and liquid crystal displays. Ceric ammonium nitrate Ceric ammonium nitrate (CAN) is the inorganic compound with the formula (NH)Ce(NO). This orange-red, water-soluble cerium salt is a specialised oxidizing agent in organic synthesis and a standard oxidant in quantitative analysis. The anion is generated by
