The hydrologic cycle involves a process of natural water distillation; essentially, rain water is distilled water, and distilled water is naturally acidic usually with a pH slightly less than 7 since it absorbs carbon dioxide which reacts slowly with water to give the bicarbonate and hydronium ions.

What is the difference between normal rain and acid rain since normal rain is acidic anyway?

Normal rain is slightly acidic but it occurs naturally, as oppose to acid rain caused by air pollution


Why is rain not naturally acidic?

Rain is naturally slightly acidic, with a pH of around 5.6, due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when it reacts with water vapor. However, this level of acidity is not harmful and is considered normal for rainwater. Factors such as pollution and industrial activities can increase the acidity of rain, leading to acid rain.

Is rain acidic or alkaline?

Unpolluted rain should be neutral but many pollutants are acidic (oxides, dioxides and trioxides of Sulphur and Nitrogen in particular). These can become dissolved in rainwater it cause it to become acidic.


What makes rain naturally acidic?

Rain becomes naturally acidic when it reacts with gases in the atmosphere, such as sulfur dioxide and nitrogen oxides, forming sulfuric acid and nitric acid. These gases are released primarily from human activities like burning fossil fuels, industrial processes, and transportation.


What is a cause of acid rain?

Although rain is naturally acidic (pH 5.6), what we consider to be acid rain occurs from polluntants, mainly sulfiric and nitric acid. They are given off by factories and cars.

What are the types of acid rain and where do these come from?

All rain is naturally slightly acidic from the dissolved carbon dioxide in it. The enhanced acid rain contains oxides of nitrogen and sulfur that combine with the water to form acids and lower the pH eve further.
