what is distilled water?

Answer 1

the ice in a freezer that occurs is distilled as it is pure

Answer 2

When you heat water to its boiling point (100 C) water vapour is given off in much larger amounts than created by simple evaporation. If boiling is carried out in a system where the water vapour can be condensed and collected separately from the source water this is called distillation as opposed to just 'boiling'. If the water vapour is channeled into a cool place it condenses back into liquid water and the distillate, as it is known, is generally more pure than the water left behind. Distilled implies purified but this only applies under rigorous conditions.

Distilled water thus is water that has been boiled and recondensed into a separate container.

Generally distillation leaves behind practically all inorganic compounds. De-ionisation, using zeolite compounds also removes most inorganic materials but is a room temperature process, not a distillation process and de-ionised water may still contain most of its organic impurities plus impurities dissolved from the zeolite filtration unit. It is thus similar to distilled water in its lack of inorganic ions but different in retaining much of its organic impurities.

Laboratories that use distilled water for accurate analytical purposes obtain distilled water by carefully distilling de-ionised water.

Answer 3

Just for the record...distilling water does NOT remove all organic contaminants, quite the opposite as in some cases it may actually concentrate them in the water. To know if an organic will be left behind when water is distilled you need to know about the boiling point of the organic contaminant and how the contaminant-water phase diagram would look.
And also for the record distilling does not generally remove inorganic contaminants - you need to make deionized water to remove those, which means running the water through serial cation/anion exchangers. Deionized and distilled do not mean the same thing!

Answer 4

Distilled water is obtained by heating it to boiling point (100C) so that it becomes water vapour; before allowing it to escape as a gas condensing it.

The purpose of distillation is to remove any impurities in the water which could slow down a chemical reaction or act as a catalyst and speed up any chemical reactions that one may plan to use the water for.

Answer 5

Distilled water is water that has virtually all of its impurities as well as electrolytes removed through distillation (boiling the water and re-condensing the steam into a clean container, leaving contaminants behind).

Distilled water is literally water that has been boiled, evaporated and condensed - leaving all chemicals, toxins and waste behind and creating pure, clean water. Distillation will remove bacteria, viruses, cysts, heavy metals, radionuclides, organics, inorganics, and particulates.

Answer 6

Distilled water is water that has virtually all of its impurities as well as electrolytes removed through distillation (boiling the water and re-condensing the steam into a clean container, leaving contaminants behind).

Answer 7

Distilled water was boiled in a closed container, the steam collected and condensed into liquid. In doing this all contaminants are removed because they would not go off in the steam.

Answer 8

Distilled water is water which is formed from the condensation of steam.It is usually associated with the distillation of impure water,or water which contains dissolved chemicals,as in drinking or spring water.Distilled water is useful in car batteries or in making up pure solutions.It is not ideal for drinking as it is tasteless.

Answer 9

condensation on windows/ice from your freezer is distiled water if kept in a plastic containerit stays distilled

Answer 10

Distilled water is water that has been boiled and condensed until it has a 100C boiling point. However there is still the presence of calcium and magnesium ions, and this can disrupt and experiment with sensitive indicators such as EDTA and Eriochrome Black T.

Water which is COMPLETELY free of everything (including ions) is deionised water.

Answer 11

Water that has been evaporated and then condensed again. The evaporation leaves impurities behind, which is why you use it in cars and batteries, etc, and why the water evaporated from the sea (which is salty) comes down as rain you can drink (because the salt was left behind!)
