Question

What the concentration of sulfuric acid I should be using to make acid rain?

Answer 1

Is it you that has been making that acid rain? Please desist.

Explanation:

Acid rain derives from the dulfur dioxide that is produced by the combustion of sulfur-rich coal:

S(s)+O2(g)→SO2(g)

And sulfur dioxide is the acid anhydride of sulfurous acid:

SO2(g)+H2O(g)→H2SO3(g)

Of couse, under some circumstances, sulfur dioxide could be oxidized up to

S03

, which is the acid anhydride of sulfuric acid,

SO3(g)+H2O(l)→H2SO4(aq)
