WebThe pH level of completely pure water is 7, which is exactly in the center of the scale, making it a neutral drink. However, most water includes particles that can raise the pH … 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).
