If rainfall occurs together with a thunderstorm, the pH of the rainwater collected will be

1. a little lower than the pH of rainwater falling without a thunderstorm
2. a little higher than the pH when no thunderstorm is present
3. not affected by the presence of a thunderstorm
4. dependent on the quantity of dust present in the air

Correct answer: a little lower than the pH of rainwater falling without a thunderstorm

Solution

Thunderstorms often produce more acidic rain due to the presence of lightning, which can convert nitrogen in the atmosphere into nitrogen oxides that dissolve in rainwater, lowering its pH compared to rain without a thunderstorm.
