WebApr 16, 2024 · In principle, the pH signal is a voltage signal caused by the activity of the hydrogen ions, measured in mV. The above equation is a straight-line equation with intercept (=asymmetry or zero point) and slope. If the above values are substituted into the slope term, a slope of 59.2 mV/pH at 298 K (= 25 °C) is obtained.
WebSo, with a pH of 8, this is in the basic range. The short answer is yes, any pH greater than 7 is typically considered basic. So a pH of 8 would be basic, albeit not extremely so.
