Why is the ionic product of water $K_w$ the same in acid, water, and alkali? [duplicate]
Seen on the web:
The concentration of [H+] and [OH−] both vary based on the the composition (acid/alkaline) of the solution, but the remarkable thing is that their product does not. When [H+] goes ...

How does one determine the probability of H⁺ to H₂O in pure water?
The ratio of $\ce{H+}$ to $\ce{H2O}$ is something around $10^{-8}$. How did people determine that?
You cannot use the $K_\mathrm{w}$, $\mathrm{p}\ce{H}$, $\ce{[H+]}$ ion concentration value to answer ...
