What would you like to do?
cuz of all the particles at the bottom and people throw stuff in it

nowhere in earth is hydrogen found in it's pure state. It is compounded with other elements.
ground water and glaciers
natural water can be found around you..in rivers, streams even underground water while pure water can rarely be found..if the water is pure it can dissolve lots of things
Pure water has a natural Ph due to the rate of dissociation to H+ and OH- is equal to rate of association to form H2O. Pure water has no free ions.
Water that is in the form of clouds is relatively pure, although it does contain some dissolved pollutants from the air. Probably the purest you could find is old glacial ice …in Antarctica, deposited at a time when global air pollution levels were much lower.
Most elements have what is known as a combining capacity, which means that they will combine with other elements - for example Iron ( Fe ) will gladly combine with Oxygen and …Oxidize, thus rusting, its still Iron but its now ferrous oxide. Silicone will also form SiO2 which is your typical sand aka Silica. Therefore, due to high presence of oxygen and other elements on earth, the chances of finding pure elements is very rare, there are very few elements which can be or exist in pure states. Such as the noble gases, which do not like to combine ( He/Ne/Ar/Kr/Xe ).
One reason is, iron will naturally react with surrounding substances to form ores. Extracting the pure iron is often a difficult and expensive process. Also pure iron ca…n corrode easily
It depends on what you mean by the pure form of Oxygen. Air is about 20% Oxygen. It comes as a molecule of two atoms of oxygen tied together. The chemical formula is O₂ but …a single oxygen would be O. A single oxygen molecule does not exist in nature.
Because it mixes with different things in the environment. Distilled water is pure.
yes, like places where there aren;t contamination
They're too reactive. They will react with oxygen or moisture in the air, so they can't exist as pure elements unless protected. The usual method is to submerse them in oil.
