What is the maximum pH value on the pH scale?

Explanation:
The numbers on the pH scale come from pH = -log10[H+], and at standard room temperature the scale is commonly defined from 0 to 14. A pH of 7 is neutral; below 7 is acidic, above 7 is basic. The highest value on this typical scale is 14, which corresponds to a very low hydrogen-ion concentration and a pOH of 0 (high OH− concentration). This is why 14 is considered the maximum on the standard pH scale. (Note: extreme conditions can push beyond 14, but 14 is the conventional upper limit taught for everyday aqueous solutions.)
