The Kilcher Homestead is a 600 acre Pioneer Homestead that has been protected for perpetuity via a ConservatIon Easement. The Kilcher Family has also preserved the Historic Cabin and site as a LIving Museum.
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.
For example: H2O can act as an acid or a base. OH (negative 1 charge) is the conjugate base if H2O is an acid (placed in a pH above 7 and loses a proton). H3O (positive 1 charge) is a conjugate acid if H2O acts as a base(placed in a pH below 7 and gains a proton). Source(s):
