Identification of sodium peroxide octahydrate?
I recently tried to make some sodium peroxide using the NaOH + H2O2 method. After my attempt I just forgot about it and let it stand for days. Now
nearly all of the water has evaporated and there are clear crystals.
How do I test if it is actually sodium peroxide and not something else?
