Izomolyar series of water solutions of sodium tungstate and D-(+)-tartaric acid by polarimetry, cryoscopy and - metry methods in a wide interval of structure has been studied. Experimental curves describing the dependences of size of a rotation corner of a polarization-plane of light, falling of temperature of freezing and pH of izomolyar aqueous solutions on structure has been compared to the corresponding curves calculated in the assumption of absence of interaction between components. On the basis of experimental data has been established, that a result of interaction between sodium tungstate and D-(+)- tartaric acid forms a product of joining with a parity of components 1:1. Dependence of specific rotation, fall of temperature of freezing and pH of water solutions from concentration of product of joining are defined. It hasestablished, that the joining product is weak complex acid. The constant of dissosation of acid has been estimated.
