Identification of sodium peroxide octahydrate?

Draeger - 29-6-2020 at 11:58

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?

I would say you have sodium hydroxide crystals, have you compared the crystal form to literature?

Apologies I missed that you said octahydrate, will which does form a clear Crystal and not yellow as I originally stated.

Shouldn't it be easy to estimate how much is peroxide, hydroxide, and carbonate, without weighing anything? A simple plan?
