Solution Chemistry of Molybdates and Tungstates

Solution Chemistry of Molybdates and Tungstates. Mo chemical shifts have been measured in several alkali molybdate solutions and Mo and Mo relaxation times measured in aqueous solutions of Na2Mo04. An extended spectrophoto-metric investigation at high dilution of the protonation of the molybdate ion strongly supports the equilibria shown in equations (7) and (8) in contrast to the previously

Aqueous solutions of Na2Mo04,2HjO have been found to form stable complexes with dicarboxylic acids of formula types [MoOjR] and The low 

From results of titration studies on the polymerization of WO the formation of HWgO f and H3Wg02i can be inferred. A number of species have been isolated in the system and the structural inter-relationships which exist between
