i was just going to share this interesting discovery (for me anyway)..... my friend has these water testing strips (he works at a pet store and needs to test aquarium water all the time(?)) sooo we bought a bottle of dasani and for some reason he wanted to check it out..... it was absolutely ACIDIC! like almost at 6.0
then we actually tested a bolthouse smoothie (which was flash pasteurised of course) and it was super-alkaline..... it just surprised me..maybe it should have? so i'm trying to get more alkaline here by drinking water and it's almost as acidic as pepsi! geeeeeeez!!!

Whether a water is acidic or alkaline, it will always contain equal numbers of positive and negative electric charges. Since alkaline water contains an excess of OH– ions, it must also contain some other kind of positive ion in addition to H+ in order to equalize the opposite charges. This extra positive ion is almost always a metal ion such as sodium, calcium or magnesium. Similarly, an acidic water must always contain negative ions in addition to OH–; the most common of these is bicarbonate HCO3–. This means that waters whose pH differs from 7 are never "pure" in the chemical sense.
