	Acids, which are weak in water are even weaker in organic solvents, and they dissolve chiefly in molecular form. The high affinity of anions to the surfaces of metal oxides (titania, alumina, hematite) induces negative electrokinetic potential of the metal oxides. The electric conductance of the dispersions of metal oxides in solutions of weak acids in organic solvents is much higher than the conductance of dispersions in the solvent (without acid) or of acid solutions (without oxide particles). A semiquantitative model of this phenomenon was proposed.

Unusual behavior of acids in dispersions of metal oxides in nonaqueous solvents
