pH 14
pH 14 : Chemistry and Chemical Disasters.An abbreviation for potential hydrogen ion. The pH numbers range form 0 to 14, 7 being neutral, and are indices of the acidity (below 7) or alkalinity (above 7) of the fluid. The numbers are a function of the hydrogen ion concentration in gram ionic weights per liter which, in turn, is a function of the dissociation of water as given by the following expression: (H) (OH) = K H2O ) = 1 x 10-14 (H2O) The pH may be expressed as the logarithm (base 10 of the reciprocal (or the negative logarithm) of the hydrogen ion concentration. The pH of a solution offers valuable information as to the immediate acidity or alkalinity, as contrasted to the total acidity or alkalinity (which may be titrated.) (Bul D11)
