"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. " - Normality vs ph

Webconcentration depends on the pH of the solution. HOCl OCl¯ + H+ at 25° C and a pH of 7.5 (7 is average for water or neutral) half of the chlorine present in a solution of OCl¯ and half is HOCl. At higher pH values, the quantity of OCl¯ increases at the expense of HOCl and at lower pH values, the shift is toward conversion of OCl¯ to HOCl. WebAs pH was decreased in equinormal solutions, both sourness and astringency increased significantly (P < 0.001). By contrast, as the normality of the equi-pH solutions was increased, only sourness demonstrated significant increases (P < 0.001) while astringency remained constant or decreased slightly.
