Well the pH over here is going to be the negative log of - Instead of writing one times ten to the negative four, I can just write ten to the negative four, and of course that's a base 10.
WebpH values are determined on a logarithmic scale. pH values are reported as a number between 0 and 14 as a standard pH unit. This unit is equivalent to the negative logarithm of the hydrogen ion molar concentration (-log(H+)) in the solution. Depending on the accuracy of the measurement, the pH value can be carried out to one or two decimal places.
