: Water can be characterized as hard or soft according to the following : Soft: 0 - 20 mg/L as calcium : Moderately soft: 20 - 40 mg/L as calcium : Slightly hard: 40 - 60 mg/L as calcium : Moderately hard: 60 - 80 mg/L as calcium : Hard: 80 - 120 mg/L as calcium : Very Hard >120 mg/L as calcium : Fresh water contains less than 1,000 mg/L : Slightly saline water contains from 1,000 mg/L to 3,000 mg/L : Moderately saline water contains from 3,000 mg/L to 10,000 mg/L : Highly saline water contains From 10,000 mg/L to 35,000 mg/L : Ocean water contains about 35,000 mg/L of salt : So the answer is that it is HARD, VERY VERY HARD to be exact
It can be both.
The 'hardness' of water is an expression used to convey the amount of mineral content dissolved in the water. The hard water minerals dissolved in the water are primarily calcium (Ca2+), and magnesium (Mg2+) metal cations. Soft water has very little dissolved minerals, Hard water has allot of dissolved minerals and usually comes form a limestone source.
When hard water is heated or evaporated these minerals come out of solution and form deposits in kettles, pipes, washing machines etc.
Yes, I think so. ---------------------------------------Not quite Soft water specifically refer to water that has low amounts of certain minerals such as calcium and magnesium and it may still contain many other dissolved materials such as chloride or sodium. Distilled water, however, is very close to pure water with nearly all dissolved materials removed through distillation.
Spring Water is soft as it contains only a few minerals.
Mineral Water on the other hand is Hard because it contains a lot of minerals including; Sodium, Calcium and Magnesium.
You can soften Hard tap water by boiling it, but it will not remove the permanently hard minerals.

I own a guinea pig, and I only let him drink Soft water. So I buy Spring Water for his bottle because hard water will cause problems with his body and will block the drinking tube on his bottle.
Yes.
The "hardness" of water is by definition the level of mineral content in the water.
Distilled water has all (or nearly all) of its mineral content removed.
Tap water (and all normal drinking water) has at least some measure of mineral content, without minerals water typically tastes a bit off or dead against the tongue.
The actual label of "Hard" water is typically reserved for extremely high mineral content, but standard tap water and any bottled water intended for drinking is going to have at least some minerals just so that it tastes decent enough to drink and is therefore at least slightly harder than distilled which is a process intended to remove as much of the mineral content as possible.
This is why most steamer, cleaning products and such recommend the use of distilled water because this "softer" water will leave behind less mineral residue when the water is steamed off or drys.
Tap water as with any water that has minerals will leave behind more residue and mineral staining if steamed away or allowed to dry on a surface. (tap water or hard water used inside a steamer for example would eventually coat the entire inside surface with mineral residue, reducing its effectiveness or causing overheating and potential fire hazard)
Hard water has iron and other minerals which distilled water doesn't have and thus is soft.
Mineral water is hard because there are minerals inside the water unlike Distilled water which has no minerals which is soft.
mineral is the hardest because hard water equal high mineral content
therefore distilled water is soft then mineral and more softer in tap
Zero because it doesn't contain any cations from Ca, Mg, Fe, Al and no others!
Soft - it contains no ions and so can not be hard
fully distilled water has no hardness therefore the soap will not lather
Water having dissolved mineral hardness of 1 GPG (grain per gallon) or more qualifies it as Hard water according to the Water Quality Association of the United States definition. If you multiply GPG rating by 1.7 you will get the PPM.
Magnesium sulfate (MgSo4) does not cause hardness of water.
In fact, it isn't even a mixture. Ice cubes and distilled water both are just water in two different states.
bi-distilled or bidistilled
fully distilled water has no hardness therefore the soap will not lather
No, distilled water is distilled water.
Distilled water. It has less bacteria and chemicals in it than tap water.
Water having dissolved mineral hardness of 1 GPG (grain per gallon) or more qualifies it as Hard water according to the Water Quality Association of the United States definition. If you multiply GPG rating by 1.7 you will get the PPM.
No, distilled water is simply water.
Distilled water is not a base.
You should not drink distilled water as it lacks minerals which are beneficial for us.Make a solution of the salt in distilled water.
Distilled water is neutral
Water (distilled or not) is a chemical compound - H2O.
distilled! :D
Distilled water is simply purified water.
Distilled water in a compound.
