The following reaction is one that happens in the atmosphere to form acid rain: SO3(g) + H2O(l) 4+H2SO4(aq)
1. We can think of this first equation as a Lewis acid/base reaction where is the acid andis the base
2. H2SO4(aq) + H2O(l) ++ HSO, (aq) + H30+ (aq) This is the dissociation of sulfuric acid which makes the rain acidic, [Select] is the acid and is the base in this reaction. is the conjugate base and] is the conjugate acid.
