Yes, negative pH is possible, but not in water as a solvent. The range of pH in water is 0 to 14 (to be more precise, it is -1.7 to 15.7, but for simplicity's sake, we start with the usual values.) Thus, what pH indicates is the ability of the acid to form H3O+, which can then donate a proton.
A neutral solution has a pH value of exactly 7 (at 25oC). See the Related Questions to the for more information about acids, bases and the pH scale. neutral. The pH value of 7.0 is considered to be neutral. Pure water has a pH of 7.0. Typically a pH of 7 is considered neutral since it is the pH of water.
