Web22 de abr. de 2005 · As an interesting anomaly let's say that the pH of "neutral" (pH=pOH) water, as a supercritical fluid, increases with temperature, the opposite to the liquid's behaviour. So, we may find a pH >11 at 250 bar and temperatures above 500 o C. Whilst a pH <5 can be attained at temperatures above 200 o C and pressures above 5000 bar.
