WebAn example of a balanced equation for the reaction of potassium nitrate with sugar is 2 KNO 3 (s) + CH 2 O (s) → 2 KNO 2 (s) + CO 2 (g) + H 2 O (g) That is the reaction that is commonly found in sparklers, a combination of potassium nitrate, sugar, and metal filings. WebAug 15, 2024 · Likewise, the reaction for peroxide formation takes the same form for both metals: \[ 2Na(s) + O_2 (g) \rightarrow Na_2O_2 (s) \label{6}\] Figure 1: Sodium explosion. from Wikipedia. Potassium. Small pieces of potassium heated in air tend to melt instantly into a mixture of potassium peroxide and potassium superoxide with no visible flame.
