What is the potential hydrogen (ph) of water?
user
The potential hydrogen of water measure how acidic or alkaline water is?  Water with a potential hydrogen of 7.0 is considered neutral water and this kind of water is typically distilled water.  Water that has a ph of less than 7.0 considered acidic water and even some bottled water has a PH less than 7.0.  Water which a PH higher than 7.0 is considered alkaline.  You can also adjust the PH of water with simple salts.  For example baking soda can be used to raise the PH of water which is acidic and lemon juice can be used to lower the PH of water that is alkaline.
