# Can sulfuric acid be decomposed by chemical change?

May 14, 2017

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

#### Explanation:

The sulfur in sulfate is fully oxidized..........i.e. $\stackrel{+ V I}{S}$. 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.

$S {O}_{4}^{2 -} + 8 {H}^{+} + 8 {e}^{-} \rightarrow {S}^{2 -} + 4 {H}_{2} O \left(l\right)$

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