Heating zinc sulphate


Hi, i need some help on this question....

What are the effects of heating zinc sulphate.

Form what i have researched i could only gather that zinc oxide is produced.

I need an equation and to know if any colour changes take place.

Thanks in advance.

Donaldson Tan:
2ZnSO4 => 2ZnO + 2SO2 + O2

Zinc Oxide produced is yellow when hot, white when cool. The colour change is due to different electronic configuration of the zinc ion at different temperature.

Zinc sulfate thermally decomposes in the range 600 to 740 C. Depending on temperature some amounts of SO3 can be expected.
