  Soluble organic acids are constantly supplied to soils as a result of the oxidative decomposition of organic matter by the plant roots and microorganisms. These carboxylic group-bearing organic molecules can interact with soil clay minerals and affect the formation and stability of organomineral aggregates. While it has been suggested that –COOH laden organics can strongly bind to broken clay edges, less is known about how such soluble acids interact with negatively charged basal clay surfaces. This work presents a Surface Forces Apparatus (SFA) study of interactions between two mica surfaces in dicarboxylic acid molecules with 2 to 7 carbon atoms. SFA allows measuring nanoscale surface forces acting between macroscopic surfaces as a function of surface separation. Since, unlike as in atomic force microscopy, the absolute surface separation in the SFA is known, it is possible simultaneously probe the adsorption of dicarboxylic acids onto mica. The results show that significant amounts of dicarboxylic acids can adsorb on mica surfaces, but only in the presence of Ca2+ ions. Ca2+ acts as cationic bridges between the negatively charged mica surface and deprotonated –COO- functionalities. In addition, the multilayer binding of larger dicarboxylic acids (C5-C7) via an assembly of hydrophobic chains is resolved. Na+ does not promote any substantial dicarboxylic acid adsorption and induce strong repulsion between mica surfaces. In summary, although these face-specific SFA measurements show that dicarboxylic acids adsorb onto mica basal surfaces only by weak forces including electrostatic, hydrophobic, and likely hydrogen bonding, they demonstrate that even such weak outer-sphere adsorption can affect adhesion between clay surfaces and play a role in the organomineral aggregate formation.
