When rain is accompanied by a thunderstorm, the collected rain water will have a pH value

Options

  1. Aslightly higher than that when the thunderstorm is not there
  2. Buninfluenced by occurence of thunderstorm
  3. Cwhich depends on the amount of dust in air
  4. Dslightly lower than that of rain water without thunderstorm

Correct answer

D. slightly lower than that of rain water without thunderstorm

Step-by-step solution

The rain water after thunderstorm contains dissolved acid and therefore the pH is less than rain water without thunderstorm.
