I have heard distilled water, then this morning it says Alkaline, or ionized. What is the best water to drink?
I just read about alkaline water. It's suppose to help keep your body alkaline. But it might not be necessary. Lemon juice is alkaline. So why not put a few drops of lemon juice in your glass of tap water?
The point of alkaline water is absorption. If the pH of the water is around 8, when you drink it absorbs more into your cells. The way this is done is an electric current is passed through the water, and split into its constituent H3O+ and OH- ions. Since water isn't perfect, the equilibrium favors slightly toward the OH- side and hence the alkalinity. Lemon juice in water is not alkaline, its acidic.
I have some additional information that I hope will clear things up about lemon juice in water:
Tap water is usually slightly alkaline (about pH 7.4). Lemon is acidic but the response it has in the body is very alkaline. In other words, if you look at lemon juice from the standpoint of chemistry, you will see it as acidic. If you look at lemon juice from the standpoint of nutritional science, it's an alkaline food. So the combination of lemon juice and water will have an alkaline result when consumed and metabolized.

Good point John. I would like to clear this other point up though if I may. The best water to drink is just pure water. Ionized or alkaline water is a myth. If the water is in fact alkaline, it wouldn't matter. Water is not metabolized by the body, so our rules of acidity/alkalinity don't apply. If the water is alkaline, it will quickly be consumed by the stomach acid, and will end up at a really low pH anyways. Don't bother buying alkaline water or whatever, I don't even know what that term really means. Mineral water maybe not so bad, but the idea behind the electrolysis of water into H+ and OH- is ridiculous. Pure water will not undergo electrolysis very well at all. Besides, the equilibrium will instantly force it back to the water side.
