Zinc oxide is white in colour at room temperature. On heating it loses oxygen and turns yellow.Now there is excess of zinc in the crystal and its form

Answer 1

Hey..!

Zinc Oxide is originally a white powder. When heated up, it turns yellow but does not decompose and when it is removed from the heat it gradually goes back to its original white color. If you heat it strongly enough to very high temperatures it will sublime without apparent decomposition.

Thanks.. :)
