Abstract The 6-molybdocobaltic acid was prepared by passing an aqueous solution of the purified ammonium salt through an Amberlite lR-120 ion-exchange coluron in the hydrogen cycle. The effluent acid was concentrated at just below room temperature by placing it in a cellophane sac and blowing a current of warm air over the outside of the sac. The molarity of the resulting solution was determined by analysis of aliquots. A portion of the effluent acid, concentrated at 40 deg by aspirating dry air through the solution for 48 hours, gave the same viscosity results as the acid concentrated by the cellophane sac methcd. Viscosity measurements were made in an Ostwald viscometer at 25 deg . The results of the viscosity determinations are recorded and may be expressed by the Jones-Dole equation. (auth)
