pH depends on ions H+ or OH-.
The pH depends on the temperature.
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
This depends on the dissolved materials.
This depends on the technological process involved.
Acidic or alkaline water ^^ the pH depends on the number of other ions but pure water is pH 7
This pH is very different and depends on the chemical nature of the waste water.
Yes, pH depends on the temperature.
The pH depends on the temperature.
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
That depends on the exact pH of the water.
pH 7 and the colour green it is neutral.
This depends on the dissolved materials.
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.
