Who me? No, chemist in R&D lab. At low and high pHs the difference

it might be useful for a student to at least be aware if it.


As long as I have no idea with whom I am talking I am keeping
activities for myself - HS studens will just get overhelmed by
the fact that situation is even more complicated - "so it is not
enough to learn which key on my calculator is for logarithm?"
