Question

Rain is called acid rain when its

  1. pH falls below 7
  2. pH falls below 6
  3. pH falls below 5.6
  4. pH is above 7

hintHint:

A normal rain has neutral pH that exists between 6.5 and 8.5.

The correct answer is: pH falls below 5.6


    Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on the environment.
    Rain is called acid rain when its pH falls below 5.6.
