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 is the pH of acid rain and normal rain?
Clean rain has a ph of 5.6, while the ph of acid rain is 4.2-4.4.
What is pH of rain water?
the normal pH of rain water is about 5.6
Why is rain not naturally acidic?
Rain is naturally acidic. As water droplets, when falling through the atmosphere, they dissolve small amounts of carbon dioxide from the atmosphere, to form a very weak acid(Carbonic Acid ; H2CO3). This acid gives rain water a very slightly acidic pH ~ 6.5 Humans and other animal life create carbon dioxide by exhalation. This is a natural process , and its absorption by rain water is also a natural process. However, because of industrial activity, more carbon dioxide and sulphur dioxide are released into the atmosphere, which is also dissolved into rain water, creating 'acid rain' in the process ; pH ~6 , slightly more acidic than natural rain water.
What is the pH of the rainwater?
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
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.
What pH is acidrain?
Acid Rain generally has a pH of less than 5, where normal rain is about 5.6. The lower the pH value, the more acidic is the rain.
If rain has a pH of 7.0 what is it considered?
Neutral. pH below 7 is "acid rain."
What is the pH for acid rain?
the answer is pH 7
What pH does normal rain have?
It has the pH of 5.6
What is the pH of rain?
A "normal" rain is considered to have a pH of 5,7. But the pH of acid rains can be as low as 2. The pH of rain is very variable on the Earth and during the year.
Why rain is naturally acidic?
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.
