A) slightly lower than that of rain water without thunderstorm
B) slightly higher than that when the thunderstorm is not these
C) uninfluenced by occurrance of thunderstorm
D) which depends on the amount of dust in air
Correct Answer: A
Solution :
During thunderstorm, oxides of nitrogen are formed by combination of \[{{\Delta }_{O}}(I)<{{\Delta }_{O}}(II)<{{\Delta }_{O}}(III)\] and \[III<I<IV<II\] which dissolve in rain water to produce nitric acid. Hence, rain water has slightly lower pH than that of rain water without thunderstorm.
