is good. 1-5;low 6-8;good/average 9-12;high
Pure water has a neutral pH of 7 at a certain temperature. Temperature only effects the pH slightly though.
Deionized water (water with all the ions removed) is pH 7
salt water has pH 6 / ph7 /ph8 depending on salt quantity
hope i helped :P
A "neutral" substance, such as distilled water.
It's actually an acidic solution. :)
Pure water has a pH of 7.0.
Water.
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
Pure water has a pH of about 7.
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.
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.

7 The pH of a neutral substance is 7. Anything higher than 7 is alkaline or basic, and anything lower than 7 is acidic.

pH ranges from 0 - 14. Ph of 0 - 6 are acidic and will turn litmus paper 'red. pH = 7 is neutral ( water) pH of 8 - 14 is alkaline and will turn litmus paper 'blue'.

An acidic substance.
The pH scale ranges from 0-14 pH. A substance that has a pH of 7 is considered to be "neutral," like pure water. A substance that has a pH less than 7 is said to be acidic, and a substance that has a pH greater than 7 is said to be basic. Therefore, the difference between those two pH levels is that the 4 pH substance is more acidic and the 10 pH substance is more basic. The more basic or acidic, the more caustic and/or corrosive the substance will be.
ammonia, milk, baking soda are just a few :) A basic substance has a pH greater than 7. An acidic substance has a pH less than 7. A substance with a pH of 7 is neutral.
