Acesulfame potassium Acesulfame potassium Acesulfame potassium ( ), also known as acesulfame K (K is the symbol for potassium) or Ace K, is a calorie-free sugar substitute (artificial sweetener) often marketed under the trade names Sunett and Sweet One. In the European Union, it is known under the E number (additive code) E950. It was discovered accidentally in 1967 by German chemist Karl Clauss at Hoechst AG (now Nutrinova). In chemical structure, acesulfame potassium is the potassium salt of 6-methyl-1,2,3-oxathiazine-4(3"H")-one 2,2-dioxide. It is a white crystalline powder with molecular formula and a molecular weight of 201.24 g/mol. Acesulfame K is 200 times
Potassium ferrioxalate Potassium ferrioxalate Potassium ferrioxalate, also known as potassium trisoxalatoferrate(III), is a chemical compound with the formula [], where iron is in the +3 oxidation state. It is an octahedral transition metal complex in which three bidentate oxalate ions are bound to an iron center. Potassium acts as a counterion, balancing the −3 charge of the complex. Crystals of the trihydrated form of the complex, []·3, are emerald green in color. In solution, the salt dissociates to give the ferrioxalate anion, [], which appears fluorescent green in color. Potassium ferrioxalate is often used in chemical actinometry, i.e. the measure of light
