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. A lightning strike can result in a cardiac arrest (heart stopping) at the time of the injury, although some victims may appear to have a delayed death a few days later if they are resuscitated but have suffered irreversible brain damage.
That's lightningâand you don't want to be anywhere near it when it strikes. Humans are good conductors. Being comprised of atoms that can transmit electrons is great for our neural network's basic functionality. But it's very bad when we drop a hairdryer in the tub, crack open an industrial capacitor, or become a human lightning rod on the links. Lightning strikes do, however, differ from the industrial shocks you'd receive from high-voltage equipment.
