That makes the formula for potassium oxide which is. Half-upright position. POTASSIUM MONOXIDE | CAMEO Chemicals | NOAA For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium peroxide, K2O2. It is majorly used in fertilizers, cement formulas and in glassmaking formulas. Alternatively and more conveniently, K2O is synthesized by heating potassium nitrate with metallic potassium: Other possibility is to heat potassium peroxide at 500C which decomposes at that temperature giving pure potassium oxide and oxygen. The steps to equate the above reaction scheme are as follows: The titration of HCl with K2O will yield significant results if a suitable indicator is used.
