The ionic product for water is defined by. KW = [H3O+][OH-] For water at standard temperature and pressure, it is 1.00 x 10-14 mol2/dm6. pKW (which is equivalent to the pH) will be 7 at room temperature, because it is the -log10 of KW, and -log10 of the square root of 1x10-14 is 7.
Lightning has been the second largest storm killer in the U.S. for the last 40 years, exceeded only by floods.
