## Humic substances have been extracted from a standard reference peat at pH 2.0, 6.0-6.5, 9.0 and 12.0 using 0.01 M or 0.001 M Na4P207. Humic acids extracted at pH 6.0, 9.0 and 12.0 showed a progressive increase in mean molecular size, as determined by gel permeation chromatography. With increasi

Models of carboxyl acidity frequently applied to humic substances (HS) are examined by potentiometric titrations of polycarboxylic acids of intermediate size (N = number of acid groups = 3-70). The unique properties of these acids are not well described by extrapolation from small (N = 1 or 2) or la
