Question

Can sulfuric acid be decomposed by chemical change?

Answer 1

The sulfur in sulfate is fully oxidized..........

Explanation:

The sulfur in sulfate is fully oxidized..........i.e. `stackrel(+VI)S`. I daresay, you could find a reaction in which sulfur is reduced.

And in fact there are sulfate reducing bacteria, which reduce sulfate to sulfide; the clever little blighters.

`SO_4^(2-) +8H^(+) + 8e^(-) rarr S^(2-)+4H_2O(l)`

It is quite sobering to think that this reaction may have been performed by the earliest micro-organisms, 3-400 hundred million years ago.
