What is the Colour of sodium peroxide?
yellow-white to yellow
Sodium peroxide appears as a yellow-white to yellow granular solid. Mixtures with combustible material are readily ignited by friction, heat, or contact with moisture.
Why is sodium peroxide yellow in Colour?
Complete answer: It is yellow in colour due to the presence of unpaired electrons in the molecule. When these unpaired electrons absorb some energy, these get excited and then show colours which are in visible range. The peroxide has yellow -white to yellow colour which is due to presence of unpaired electrons.
