Ph value of the substance
WebApr 26, 2024 · Function. The pH range is from zero to 14, with zero being the most acidic, 14 being the most basic, and seven being neutral. In healthy humans, normal body pH is between 7.35 and 7.45, with an average of 7.4. 1. This slightly alkaline pH level is ideal for many biological processes, such as the oxygenation of blood. WebThe pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.

Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic.
WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization constant, Kw, with temperature. At 25°C we know it to be 1.0 x 10^ (-14), but at something like 50°C it's about 5.5 x 10^ (-14).
