It is based as salt water but then turned into pure water. 1. The ocean water evaporates into water vapor leaving all the salt and other chemicals behind 2.The water vapor turns into clouds 3.The clouds build up in water so much they rain. So yes rain water is pure

What is the pure form of water- rainwater or groundwater?
As i fell ground water is the purest form of water. As rain water may consist bad Bacteria but ground water does not as it is purified by the ground.
Is rainwater is pure water?
No, it is not always pure. In nature it is considered the purest form of water, which it is. However as it falls to the ground it mixes with a large number of impurities present in the air and hence becomes impure.
What to do to simulate rainwater on your plants?
The best way to simulate rain water for your plants is to use distilled water. It will provide a pure form of water which is free of chemicals found in tap water.
What is the pH value of unpolluted rainwater?
Pure water has a ph of 7.
Is ocean water and pure water and rainwater are mixtures?
yes its made of oxygen and hydrogen
Does rainwater have vitamin B12?
No, rainwater would be pure water if it weren't for the contaminates is picks up from the air while falling.
Can rainwater have a pH of 7?
Pure water (distilled and non-aerated) would have a pH value of 7.0
Rainwater is the purest form of water - true or false?
Yes, it is true but pure rain only I have said so because today we experience acid rains as well.
What percentage of earths water is pure?
Virtually none. Ever fresh rainwater or snow has dissolved impurities in it.
Is rainwater a poor conductor?
To produce rainwater, it first evaporates, only collecting pure water with nothing else, then it condenses into clouds, that are still made of pure water. When it becomes rain, it is still pure water, so it will not conduct electricity well. It's molecules carry no electric charge and there are no ions in solution to carry charges, so it would not be a good conductor.
Rain water before it hit the ground is what type of water?
I'm assuming the question to be as follows What is the purest form of water? The purest form of water would be where every molecule in the given container is 2 parts Hydrogen and one part Oxygen. Rainwater is considered one of the purest forms of water because it is essentially the process of distillation used in laboratories to generate high purity water. However, Rainwater does contain traces of minerals, dust, pollutants from the atmosphere etc., But for all practical purposes, Rainwater is one of the purest forms of water. However 100% pure water is close to impossible to create. Just the way 100% pure vaccum or 100% pure gold. There are bound to be contaminants at the most microscopic level. The contaminants are usually measured as ppm (Parts Per Million). The permissible limit varies from country to country depending upon the standards of living but 500 ppm or less of dissolved solids can be considered pretty pure.
Calcium carbonate is insoluble in pure water why does it dissolve in rain water?
Because rainwater, with the different chemicals and elements in it, is very slightly acidic.
