Simple pH Question

    Here's a quickie. Since the pH scale is based on powers of 10, would a pH of 12 indicate that a substance is 10^6 times more basic than a substance with a pH of 6?

    No. pH is not a property of the substance, it is a property of the solution.

    106 is the ratio of concentrations of H+ (or OH-), not directly related to substance basicity.
