I was just wondering why is it that we use log in order to find the pH?

We use the log scale because it is easier to quantify pH on a scale from 1-14 instead of using their [H+] values.

We use log because the p in pH represents -log. As such, pH is the -log([H3O+]. This is similar to pOH, which is -log([OH-]).
