Resumen
A potentiometric study of the acid-base properties of humic acid was made with the objective of determining the pK(a) value and concentration of each titratable group. The use of linear equations in the treatment of titration curves led to the characterization of six titratable groups, which permits the acid-base properties to be explained and will be useful in studies of soil and environmental chemistry. 257 1 35 39
