The pH of natural, unpolluted rainwater is typically around 5.6.<\/section>\n
Rainwater is naturally slightly acidic because carbon dioxide (CO2) from the atmosphere dissolves in it, forming weak carbonic acid (H2CO3).<\/section>\n
Acid rain, caused by pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx), has a pH lower than 5.6. Pure water has a neutral pH of 7.0, but rainwater is never pure due to dissolved atmospheric gases.<\/section>\n","protected":false},"excerpt":{"rendered":"
