Acid Rain and How to Fight it
The accurate term for this phenomenon is acid precipitation,as it does not only occur with rain. When saying acid rain, we generally refer to the deposition of acidic components in rain, snow, fog, dew, even to dry particles.
The rain is always a bit acid, due to the excistence of carbon dioxide in the earth’s atmosphere. When it exists in small quantities, it reacts with water to produce carbonic acid, which is weak and harmless. So, clean or unpolluted rain has a slightly acidic pH of 5.6 (having grade 7 as neutral) However, this is not the case when we talk about acid rain.
