In chemistry, peroxydicarbonate (sometimes peroxodicarbonate) is a divalent anion with the chemical formula C2O2−6. It is one of the oxocarbon anions, which consist solely of carbon and oxygen. Its molecular structure can be viewed as two carbonate anions joined so as to form a peroxide bridge –O–O–. The anion is formed, together with peroxocarbonate CO2−4, at the negative electrode during electrolysis of molten lithium carbonate. The anion can also be obtained by electrolysis of a saturated solution of rubidium carbonate in water. In addition, the peroxodicarbonate anion can be obtained by electrosynthesis on (BDD) during water oxidation. The formal oxidation of two carbonate ions takes place at the anode. Due to the high oxidation potential of the peroxodicarbonate anion, a high anodic overpotential is necessary. This is even more important if hydroxyl radicals are involved in the formation process. Recent publications show that a concentration of 282 mmol/L of peroxodicarbonate can be reached in an undivided cell with sodium carbonate as starting material at current densities of 720 mA/cm². The described process is suitable for the pilot scale production of sodium peroxodicarbonate. K2C2O6 was obtained by and in 1895; its crystal structure was determined only in 2002. It too can be obtained by electrolysis of a saturated potassium carbonate solution at −20 °C. It is a light blue crystalline solid that decomposes at 141 °C, releasing oxygen and carbon dioxide, and decomposes slowly at lower temperatures. is a light blue crystalline solid that decomposes at 424 K (151 °C). Its structure was published in 2003. In both salts, each of the two carbonate units is planar. In the rubidium salt the whole molecule is planar, whereas in the potassium salt the two units lie on different and nearly perpendicular planes, both of which contain the O–O bond. (Wikipedia).
Making Calcium Peroxide (CaO2)
In today’s video we are making calcium peroxide from sodium hydroxide, calcium chloride and hydrogen peroxide. Calcium peroxide is an oxidizing agent and it could be used to make oxygen by simply heating it. Our yield was low but we managed to make some. Just to put it somewhere: the produ

Epoxidation of Alkenes - DMDO, mCPBA, & NaOCl (IOC 26)
In this episode, I discuss the epoxidation of electron-rich and electron-poor olefins, using peracids, DMDO, hydrogen peroxide, and sodium hypochlorite (NaOCl). *Note: for some reason, I didn't manage to pronounce MMPP correctly; it's full name is magnesium monoperoxyphthalate. *WARNING*
