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.
Generally, water has a pH level of 7 (which is neutral) or 8 on the pH scale of 1-12. Acidic substances have pH levels between 1-6 while alkaline substances have pH levels between 8-12. To give you a better understanding of what substances are acidic and which ones are alkaline, regard the following scale: Though tap water leaving water plants usually has a pH level ranging from 6.5-8, it often changes when traveling through pipelines to our homes.
