Measuring the pH of rainwater outside during a shower. The electronic pH meter shows that the rain has a pH of just below five, meaning it is weakly acidic. Rainwater can be acidified by air pollutants, especially nitrogen and sulfur oxides, which are emitted by industrial processes. Natural unpolluted rain has a pH around 5.7, as carbon dioxide in the air also acidifies atmospheric water.
