Dear phD School sifus,  notworthy.gif

I have a question in mind (for a long time already) haha.... I tried looking from books and the internet for answers but I'm din't really find much  cry.gif
I was wondering whether you guys could clarify, what's the differences between:

1. Pipe water
2. Rain water
3. Distilled water
4. Deionized water
5. Battery water

We are using some of these waters in our lab but it would be good to know if I can actually use different type of water for different processes i.e. PCR etc..

As for those in our daily lives... one thing which I'm very interested in is.... what type of water can we actually use for our car's battery? Some say battery water, some say distilled water... very confused  rclxub.gif

Hope you guys can help me out, thanks thanks, appreciate your help!  notworthy.gif  notworthy.gif

Fundamentally, all contains H2O(obviosuly) it is the chemical and physical content difference that makes it differ from one and another

1) Pipe water is the water that is cleanse to make it potable... so, it is safe interm of chemical, biological and other properties, that makes it safe to drink or other domestic usage like bathing(direct contact with skin that does not cause irritants)

2) rain water is the evaporated water(theoretically to be distilled water when it accumulates above the clouds. but when rain falls, it absorbs some properties of the atmosphere(polluted air due to industrial fume waste) that makes it acidic as per some forumers said.

3) this is the totally pure water, with no minerals, biological contenct etc....

4) not that familiar with this though

5) this is known as heavy water

Heavy water is the stuff they use in nuclear reactors. This is definitely not battery water used in car batteries.

My mistakes... sorry...

battery water, is actually distilled water.

if so, then my friend during schooling time wont be hospitalized by drinking battery water LAA doh.gif

and to Awakened_Angel, distilled water is NOT for drinking la. since it is so pure, it is very hypotonic. When drank, it will cause excess water entering into our body cells, causing them to burst. Google deplasmolysis or cytolysis.

When famine breakout, and no potable water, evaporated and condensed distilled water is the only water that is safe to drink and easiest to obtain.

The problem that excessive distilled water cause it since there are no minerals within it, it tends to absorb minerals from body which leads to demineralization of body

and it does not absorb minerals from the body la.  doh.gif  it causes osmotic imbalance which results in cells bursting.

I am from Engineering background.. not medical.. to me, the flow of substance is absorb

it is like people argue about the terms for place to urinate... toilet? washing closet? lavatory? aint it the same? but use differently in different place

but that isn't really really pure distilled water.

those distilled water u get in labs are distilled and condensed for at 3-4 times, hence it is 100% free of minerals and other contaminants.

when famine breakouts, i doubt people have the time and energy to conduct distillation a few times.

Yes... I am talking about possibility of drinking distilled water as in general.

and yes too to your assumptions that people do not have the time and energy to do distillation several times...

100% maybe required for medical purposes... but for survival purposes? not quite... and what does 95% pure and 99% pure have to do with keeping me hydrated....

ok. so how do you justify that the distilled water will 'absorb the minerals' when the water itself is already in the bloodstream?

It is my assumptions... further discussions from medical POV will only shed my ignorant biggrin.gif

yes..minerals leave our body all the time...due too the regulations of the ions in our body, minerals not taken in by the cells but not due to the reasons Awakened_angel given..

That is what I read, sorry if I am wrong...

that since distilled water are so pure, they tend to'absorb" other mineral/particles to get equilibirum....

I am more familiar with water properties from physical properties outside human body
