A pH or minus 4.5 or -4.5? Does a negative pH value exist like
negative temperrature reading.I can not rememberr from my general
chemistry class several decades ago. that if its possible for the
hydrogen ion concentration to have negative values?

How can that be feasible a pH range from 1 to 14.From what I remember,
The lower values is in the acidiic side(units 1 to 6) while the pH
readings starting from above 7 is going to the alkaline side. The
middle value 7 means neutral.
