Ph in log
WebbNow, to find the difference in magnitude between Loma Prieta EQ, we cannot just subtract the magnitudes. Because remember that our scale was of base 10 logarithmic and in logarithmic scales, moving a distance means multiplying in value. So, the 1.2 difference between 7.0 and 5.8 really equals 10 raised to 1.2th power which equals roughly 16. Webb6 maj 2024 · pH is a logarithmic measure of the hydrogen ion concentration of an aqueous solution pH = -log [H +] where log is the base 10 logarithm and [H +] is the hydrogen ion concentration in moles per liter
