Formation of complexes of Ge(IV) with chromotropic acid (GeL8-3), with maltol and kojic acid (GeA2(OH)2 and GeA+3) and with mannitol and sorbitol (GeL2(OH)- and GeL2-3) has been studied by the method of potentiometric neutralization titration in diluted aqueous solutions. Equilibrium constants of the reactions of germanic acid with the mentioned reagents have been determined
