WebThus, most tap and bottled waters (typically pH 6.7 to 7.4) would not be expected to affect pepsin stability. The purposes of these in vitro studies were to investigate whether artesian well water containing natural bicarbonate (pH 8.8) might irreversibly denature (inactivate) human pepsin, and to establish its potential acid-buffering capacity. WebpH = -log[H+] = log 1/[H+] The pH scale ranges from 0 to 14, with 7.0 being neutral. Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2.
