Why is water considered to be neutral?

Explanation:

Because it has a pH of 7, water is considered to be neutral. It is neither an acid nor a base but is the reference point for acids and bases.

Clara’s answer is essentially correct; but a little more might help to make the point. To Discuss pH, the concentration of [H+] is given in this way: pH = - log [H+]. In pure water, that concentration is 1 x 10^-7, the log of which is -7, the opposite is 7, thus the pH = 7. The [OH-] is also equal to the [H+], and is an ideal way of saying pure “water is equally as acidic as it is basic”, and is therefore neutral.
