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
pH depends on ions H+ or OH-.
pure water is neutral with a pH of 7
In a solution (in this case, sand), a Ph rating of 7 or "neutral" is given if the number of Hydronium ions is equivalent to the number of Hydroxide ions.
Yes, a pH test is one of a number of tests that can show water quality. Water that is too acidic or basic (alkaline) is generally considered bad.
The water is nutral so it is at Ph 7
Acidic or alkaline water ^^ the pH depends on the number of other ions but pure water is pH 7
pH 7 and the colour green it is neutral.
pH depends on ions H+ or OH-.
it is neutral. Water is a 7 on the pH scale
7 is the perfect number for pH.
The figure 7 is normally taken as neutral pH in water.
Water has a neutral pH of 7 because the number of hydrogen ions (H+) produced by dissociation is equal to the number of hydroxide ions (OH-) produced, resulting in a balance of acidic and basic ions. This self-ionization of water maintains a neutral pH in pure water.
pure water is neutral with a pH of 7
its neutral so the number would be 7
Highly polluted water with acid typically has a pH below 6.5. Acidic water can have a pH ranging from 0 to 6.5, indicating a high concentration of hydrogen ions.
The fluid in a battery, sulfuric acid and water, has a ph around 1.
