Potassium peroxydicarbonate
« on: November 16, 2019, 12:00:46 PM »
Is it possible to obtain Potassium peroxydicarbonate by passing CO2 through KO2 at 0 ° C in absolute ethanol? What equation describes this process?

In my knowledge it can only obtained by electrolysis.

Ethanol is a solvent for this reaction. The reaction itself is very simple. Just try.

In the interaction of 71 g of potassium peroxide with carbon dioxide at 0 degree C in absolute ethanol, a white substance powder was obtained in 80% yield. What is an amount of solid residue (in g) which can occur after complete decomposition of the substance by heating.

Start from a balanced reaction.

Start from a balanced reaction.
reaction KO2 + CO2 = K2CO3 + O2 does not fit the condition, and KO2 + CO2 = K2C2O6 is not equalized because there is no deoxidant

Nothing is balanced in your equations? Do this first. KO2 is potassiumhyperoxide.

Simple, but explosive? Superoxide and fuel.

So far we are talking about writing and balancing reactions.
