If water is so good for you then why does it RUST pipes???

Rust is the substance formed when iron compounds corrode in the presence of oxygen and water. It is a mixture of iron oxides and hydroxides. Rusting is a common term for corrosion, and usually corrosion of steel.\n\nIron is found naturally in the ore haematite as iron oxide, and metallic iron tends to return to a similar state when exposed to air, (hydrogen, oxygen, nitrogen, etc.) and water. This corrosion is due to the oxidation reaction when iron metal returns to an energetically favourable state. Energy is given off when rust forms. The process of rusting can be summarized as three basic stages: The formation of iron(II) ions from the metal; the formation of hydroxide ions; and their reaction together, with the addition of oxygen, to create rust.\n\nIron is the main component of steel and the corrosion of steel is observed more frequently, since iron is rarely used without alloying in the present day.\n\nWhen steel contacts water, an electrochemical process starts. On the surface of the metal, iron is oxidized to iron(II):\n\n    Fe → Fe2+ + 2e−\n\nThe electrons released travel to the edges of the water droplet, where there is plenty of dissolved oxygen. They reduce the oxygen and water to hydroxide ions:\n\n    4e− + O2 + 2H2O → 4OH−\n\nThe hydroxide ions react with the iron(II) ions and more dissolved oxygen to form iron oxide. The hydration is variable, however in its most general form:\n\n    Fe2+ + 2OH− → Fe(OH)2\n    4Fe(OH)2 + O2 → 2(Fe2O3.xH2O) + 2H2O\n\nHence, rust is hydrated iron(III) oxide. Corrosion tends to progress faster in seawater than fresh water due to higher concentration of sodium chloride ions, making the solution more conductive. Rusting is also accelerated in the presence of acids, but inhibited by alkalis. Rust can often be removed through electrolysis, however the base metal object can not be restored through this method.

It does rust.  Due to the form it takes, it takes on oxygen molecules, carrying them with the iron for a time until it is released farther into the body.  If your blood's iron was blocked from combining with oxygen, what we call "rusting", you would die from lack of oxygen.

Yes, water is very good for you.  http://www.watercure.com/

That sounds incredibly ropy, the water will combine with other contents of your stocmach. the second that occurs, one thing the water isn't, is pure!!\n\nIt is true that drinking *any* reasonably clean water to great excess can cause problems because you start removing salts from your body when you urinate.\n\nLosing electrolyte due to drinking gallons of water in a short space of time (can easily be fatal) is totally different than blaming it on the water being "too pure".\n\nI think I would counter your lab workers comments by asking them how many seconds they feel it takes the water to reach your stomach. Then after they ave said "ooh, about 1 perhaps", then ask them if the water would still be pure - swimming around with dil Hcl and the remains of the mornings breakfast.\n\nThen remind them of the ultra-pure water leaching out the "nutrients".\n\nNutrients?   And where would these leached nutrients "go" ?  Would they be filtered out by the kidneys (retained) ?\n\nLOL I am going to have to stop now or I could write for ages on this and I really need to do a little more work!

the water in the tank not boul is good drinking water

Well water can over time through a process called weathering, other than that acid is excellent, that is how acid rain is effecting us.\nAlso salt and a number of other chemicals and solvents.

You are either drinking water  with more calcium at some times or it's in the food you are eating.  In places there is more calcium in country deep wells than in city water wells which filter such things as lime deposits.

A few things first:\nPure water can mean two things: Actual pure H2O, or distilled water, with no minerals or anything but water. Bottled water is really either spring or tap water that has been filtered.\n\nYou don't want to drink only distilled water. I've tried it, and due to the lack of minerals that are found in either bottled or tap water, I experienced severe muscle cramping all over my body within 1 1/2 days. Generally, people receive the necessary minerals for their body to work properly through water. Removing those minerals causes deficiencies, which makes your body not function properly.\n\nDrinking enough bottled water or tap water (there is a difference, but it is only minor in the US) is necessary because: 1. Your body is made up of over 70% water, and it is required to keep your body function properly. 2. Water helps the body remove waste. 3. It provides the necessary minerals that are so hard to get from any other source.\n\nIf you do not drink enough water daily, the results can be dehydration, a build up of toxins and waste within your body, and if severe enough, is a cause of death.\n\nGenerally, tap water is tested regularly by the local, state, and federal governments, and is safe to drink. Some countries prefer bottled water because the tap water is not safe to drink. This is not the case in the US.

because water is a renewable resource. There is as much water on the earth today as there was when the earth formed.  The argument that not all of that water is as drinkable today as it was then is a weak one. The water from a treatment plant (post treatment) is usually cleaner than plain tapwater!

you need to drink water to have good health\ngo to this website and read more about it\nhttp://nutrition.about.com/od/hydrationwater/a/waterarticle.htm

Yes because of the water. The first and most important rule in plumbing is that eventually a gasket will leak. So you must be prepared. Maybe one in a million. You take the chance ?

if iron comes into contact with moisture and air, it starts to rust.The surface of iron is painted because it prevents iron from coming into contact with air and moisture.

Rust can harbor Tetanus if it is found in the environment like a barbed wire fence or rusty nail.  The ill effects of Tetanus are from the exotoxin secreted by Clostridium tentni, a bacteria.  This needs to enter your bloodstream rather than ingesting it to cause serious troubles.\n\nRust itself out in the environment is ferrous oxide.  That found in water is mostly in the form of ferrous hydroxide.  If you ingest a little rusty water as it comes out of the tap, there is no problem.  But like virtually anything else if you make it a regular diet and ingest a lot of rust then you can overdose.  \n\nOverdose amounts are about 0.5mg/kg of body weight (2.2lbs per kg).  The effects of toxic doses of iron are characterized by initial depression, rapid and shallow respiration, coma, convulsion, respiratory failure and cardiac arrest. Diarrhea and vomiting also occur. \n\nCheck out the link below which goes into more detail if you need it.

salt doesnt have as much effect on rust.... where rust comes from is oxygen reacting with the iron in your vehicle....\n\nso when water (H20) comes in contact with iron (Fe) it creates iron oxide...rust(FeO2)

Yes it does. Corrosion is when the metal oxidises.

bottled water being healthier is a myth\nits the same water you are drinking from your tap only they add stuff to improve the taste\nan interesting fact is that bottled water is regulated by the FDA (probably one of the worst agencies in the country) and grossly under staffed   fewer inspectors\ntap water is governed by the EPA and public water supplies are heavily governed and watched    the FDA tested bottled water and found 40 % failed there test and most had arsenic level  much higher than the average tap water so enjoy that 2.00 bottle of water   mine is free     Penn add Teller had a good episode on bull shit concerning this topic

sometimes, your own perspiration causes metals to corrode.  This has to do with the composition on your sweat.  It's the same reason that some jewelry that isn't gold turns green after a while.
