Zinc sulfate is produced by reacting zinc oxide with which substance?

You want zinc sulphate

1. You get the zinc part from zinc oxide
2. Now you need a source of sulphate. The simplest seems to be : sulphuric acid .
3. And you can write a balanced equation:
4. ZnO(s) + H2SO4(aq) → ZnSO4(aq) + H2O(l) .

With sulfuric acid…? And we could write the stoichiometric equation…

[math]ZnO(s) + H_{2}SO_{4}(aq) longrightarrow ZnSO_{4}(aq) + H_{2}O(l)[/math]

I think the heptahydrate, [math]ZnSO_{4}•7H_{2}O[/math], could be crystallized from such a solution…
