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?



Collected elements:
Al, Cu, Ga, C (coal), S, Zn, Na

Collected compounds:

Inorganic:
NaOH; NaHCO3; MnCl2; MnCO3; CuSO4; FeSO4; aq. 30-33% HCl; aq. NaClO; aq. 9,5% ammonia; aq. 94-96% H2SO4; aq. 3% H2O2

Organic:
citric acid, sodium acetate, sodium citrate, petroleum, mineral oil

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?
