WebThe 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. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. 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).
