Answer 2

Explanation:

sulphur dioxide is very soluble in water. when water is added to sulphur dioxide ( i.e. sulphur dioxide react with water or rather SO2 is bubbled through water ) , H2SO3 is formed. that is a reason why SO2 is blamed as the key gas for causing acid rain. It combines with H2o in atmosphere to form the very strong acid ,sulfuric acid. at first , sulfurous acid is formed when So2 is passed through H2o

So2 + H2o = H2SO3

sulphurous acid is weackly dibasic acid. sulphur dioxide is a major component of acid rain since it mixes with vapour in the atmosphere reacting to produce H2So4 .

statics are available on So2 levels from 1974 to 1998.
