Abstract
The Potential — pH diagrams are presented for water over the temperature range 298.16-573.16º K. The diagrams are discussed with reference to variation of the thermodynamic stability of species H20(l) , H +, 0H-, H-, H202, H0-2, H1, H2, 02, 0S and H20(g) with temperature. The diagrams demonstrate the variation of Kw and the neutral point of water with temperature. The maximum for Kw was —11.86 at 473.16º K (200ºC) with a corresponding minimum pH value of 5.93.
