QUOTE(highwind85 @ Sep 29 2010, 11:17 AM) skin absorb water, yes.. cells burst, no... http://www.scientificamerican.com/article....gers-wrinkle-in Added on September 29, 2010, 11:23 amhaha..we are all learning...what you're saying is "diffussion" which is valid without the involvement of semi-permeable membrane.. Osmosis is applicable for biological system due to the presence of semi-permeable membrane (Cell membrane/ cell wall)... Ah..this brings me back my memories of spm bio experiment where you soak potatos in isotonic, hypertonic and hypotonic solutions.. LOL.... I remembered stealing some potatoes home to cook french fries Bad example, don't learn guys haha

QUOTE(zstan @ Sep 28 2010, 12:22 PM) like what Eventless mentioned, the batteries are lead acid. but without H20, dry acid itself cannot exhibit acidity and hence the use of distilled water which is pure of any contaminants. sos from wiki. 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. What makes pure water hypotonic? are you saying that water distillers kill people? This post has been edited by wodenus: Sep 29 2010, 06:50 PM

No it won't kill you.
Yes distilled water is hypotonic. But so is pipe water. Pipe water has some minerals, but not that much. Hypotonic does not mean toxic.
If you drink pure distilled water your entire life, you will not die, or even get sick. Because you're still eating. And most of the minerals your body needs comes from your food, not from the plain water you drink.
Once the water you drink enters your body, it is absorbed into your blood stream. It is not kept separate. So the proposed experiment with soaking your hand in water is irrelevant. Your cells in your body will not be floating around in a solution of pure distilled water.
So, if drinking water is hypotonic, why does it not cause all your cells to die? The answer is obvious. Don't drink so much water all in one go. If you drink 4L of water all in one go, you might get water intoxication and die. But why would you want to drink so much water? Your body has a built in mechanism to control the balance of water and ions in your body. Everyone has it from birth. Trust your thirst reflex. It's worked well for billions of people for thousands of years.

My point is pipe water has so little mineral, it is nearly identical to distilled water. At least when it comes to nutrition and tonicity.

the difference is in its pH in addition to the minerals n microorganism contain inside.
