Rainwater is typically pure water, with only trace amounts of other substances. Tap water can be filled with all sorts of garbage, depending on where you live and how diligent the authorities are about cleaning it first.

Rainwater is H2O (pure water) mixed with whatever it picks up from the surrounding air when it forms. Sooo rain that falls over the open ocean is a lot different than rain that falls over a major industrial area. Your State Department of Natural Resources could tell you what is in your tap water but that might be something you really don't want to know

What Is In Rainwater

Answer 5

Rain water is pretty impure. Any air borne impurities will appear in the rain and the size of the particals can also have an impact on the size of the rain drops. Also rain is natures fertiliser. During a thunder storm Nitrogen in the air is combined with oxygen when the electrical charge from ligtning is present. This forms Nitrates NO3 which are the basis of fertilisers that you but over the counter. Thats why everything is greener after thunder storms.

Tap water could have anything in it but ones that tend to be prevelent everywhere are Sodium, Chlorine, Potassium, and also a lot of places put flurine in the water to help with the quality of peoples teeth.

Answer 6

Generally, rain has a pH slightly under 6. This is because atmospheric carbon dioxide dissolves in the droplet to form minute quantities of carbonic acid, which then partially dissociates, lowering the pH. In some desert areas, airborne dust contains enough calcium carbonate to counter the natural acidity of precipitation, and rainfall can be neutral or even alkaline. Rain below pH 5.6 is considered acid rain.

Answer 7

Rain is part of the worlds way of filtering the air. Any kind of dust and pollution that go into the air clings to the moisture and falls as rain. Then the particles are filtered into the ground. So rain water can have small traces of any airborne substance in it.

A volcanic eruption in the world should produce a rainy period for the world as it is filtered from the atmosphere.

Answer 8

Rainwater is the Kidney in the sky. The water falls to the bladder, oh, I meant to say the earth, and then, well, you know, it comes out the tap! If you really want to know what's in tap water, look in the web under "hazards of chlorine in tap water." You will find what's in the water and why chlorine is dangerous even after killing the bacteria.

First of all, the water from rain has traditionally been known by humans as well as animals as the purest source of water.
After years of industrial pollution most especially from coal sources, we (the worlds mostindustrialized areas) now have acid rain. Acid rain is a product of high emissions of sulphur dioxide and oxides of nitrogen from industrial sources
Regular rain has water from the rain clouds, particulates in the atmosphere on its way down, and depending on the area, chemicals such as the ones listed above.
