Can you purify rainwater?
Rainwater can be filtered for drinking as long as you have a clean catchment surface and you use a proper filter. Water for the whole house can be filtered using a uv filter or quantum filtration system or you can use a gravity filter such as a Berkey Water Filter just for your drinking water.
What pH is rainwater?
Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
Why is rainwater better than tap water?
Answer: Rainwater tends to be way more pure than tap water, city or well. Rain contains few salts, minerals, treatment chemicals or pharmaceuticals often found in municipal tap water. Though relatively pure, rainwater can contain particulates from the atmosphere, such as dust or pollen.

What chemicals are in rainwater?

How do you test if water is pure?
The purity of water can be tested by evaporating it (to dryness) on an evaporating dish or by measuring its boiling point.
How can we purify rainwater for drinking?
Boiling. For emergency or short-term use of rain barrel water for drinking, boiling is the best way to purify it because boiling kills viruses, parasites and bacteria that cause diarrhea.
Is rainwater freshwater or saltwater?
As the water vapor is lifted it cools. As it cools it condenses and forms a cloud which then could produce rain. However, since the salt was left behind in the evaporation process any rain that falls would be salt-free water.
