Answer:
pH is a measure of the amount of Hydrogen ions (H+) in a solution. ... Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That's why 7 is neutral.

Answer:
The ph of water at 15°c is
Explanation:
It's dependent on the ionic product of water which happens to be 10^-14 at 25°C.
Now pure water is neutral so it has an equal concentration of H+ and OH- ions.
Now
10^-14= [H+]×[OH-] and H+ and OH- are equal in concentration.
Which gives [H+] as 10^-7.
pH is defined as the negative logarithm of [H+].
Going by this definition pH of pure water at 25°C is 7.
