Answer 2

Answer:

That question is actually misleading! In fact, pure water only has a pH of 7 at a particular temperature - the temperature at which the Kw value is 1.00 x 10-14 mol2 dm-6.

This is how it comes about:

To find the pH you need first to find the hydrogen ion concentration (or hydroxonium ion concentration - it's the same thing). Then you convert it to pH.

In pure water at room temperature the Kw value tells you that:

[H+] [OH-] = 1.00 x 10-14
