The water molecule is made up of hydrogen and oxygen, H2O. One of the hydrogen atoms is able to leave the water molecule, leaving behind OH- and H+. This happens, to a certain degree, in pure water such that in every liter of water, 10-7 moles of water will dissociate into OH- and H+. This is described by the equilibrium constant of water deprotonation.
pH is calculated as -log10[H+]. Because [H+] = 10-7, pH = 7. We consider this "neutral" because it is the pH that our bodies, and most of the rest of the biological organisms found in nature, use.
Pure water has a neutral pH value of 7, anything above 7 is alkaline and anything below 7 is acidic.
pure water is neutral with a pH of 7
Because water is completely neutral, since it is HOH, which means equal number of hydrogen and hydroxide ions.
the pH value is 7.38 exactly which is then considered as 7.4
A chemical can be identified as an acid by testing its pH. A pH value less than seven is considered acidic, while a pH value greater than seven is considered to be a base, or alkaline. Pure water has a pH value of seven.

Pure water has a ph of 7.
Pure water has only one value of pH, that is 7, which is the pH for a neutral solution.
Pure water (distilled and non-aerated) would have a pH value of 7.0
Normal water contains impurities and minerals, so during boiling, these impurities are expelled, but this changes the pH value a little, thus the pH value would be about 7. Boiling pure water (pH7), will result in boiled pure water being at pH value 7, as there are no impurities or minerals in it
Pure water has a neutral pH value of 7, anything above 7 is alkaline and anything below 7 is acidic.
If your question is what is the pH of pure water, then the answer is seven, which means water is neutral.
pure water is neutral with a pH of 7
Because water is a neutral and high pH values are basic and low pH values are asidic.
At 100C the pH of pure water is 6.14 which is neutral
The solution of pure sodium chloride is neutral.
Because water is completely neutral, since it is HOH, which means equal number of hydrogen and hydroxide ions.
