WebAt very high pH, generally > 10, most glass electrodes become responsive to both H + and Na +, with the measured pH being lower than actual. At low pH, typically < 1, glass membranes are susceptible to saturation by H +, and produce pH readings that are higher … WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion …
