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.
Thus, under normal conditions it will always maintain a neutral 7.4 pH. Water pH will automatically change when it is ingested and comes in contact with food in your stomach. Some examples of water pH and beverage pH levels: The truth is, people drink acidic beverages all the time, they are just not aware of it.
