the pH of water is 7 because 7 means that it is neutral. everything has a pH above or below because nothing else is completely neutral.
Distilled water would have a pH closer to 7, as it is neutral.
The pH of water is 7 http://en.wikipedia.org/wiki/File:PH_scale.png
The water is nutral so it is at Ph 7
Distilled water, if it is truly distilled to purity, has a pH of 7. This means that the concentration of hydrogen ions dissociated from the water is 1x10-7 mol dm-3. Often, distilled water is impure, and is slightly more acidic (it has a slightly lower pH than seven).
Pure water has a pH of 7, which is considered neutral on the pH scale.
Water (when it is pure) has a PH of 7. This is the most well-known substance with PH 7 but there are many others (most of which are water-based solutions) which have a PH of around 7.
Pure liquid water has a neutral pH of 7.
No, acids have a smaller pH than water. It is usually <6 and pure water has a pH of 7.
Water. 7 is a neutral pH- not acid, not alkaline.
Yes....water has a ph level of 7 (neutral)
The pH level of pure water is 7, making it neutral.
The pH of pure water is 7
Neutral. A.K.A pH.7
Methane (CH4) has a neutral pH, around 7
Purified water should have a pH level of 7. The values of 7 is neutral on the pH scale.
Pure water is neutral, with a pH of 7. However, water can become slightly acidic or basic by dissolving substances in it.
