Abstract: In Na2WO4 and Na2MoO4 water solns. acidified with HNO3, isopolyanions are formed, accompanied with pos. volumetric changes. The curves of the relation of the dilation Δ V to the compn. of the soln. have max. at ratios 1.7 H+:WVI and 1.5 H+:-MoVI. The ratio 1.7 H+:WVI is different from the results of conductometric titration. The ratio 1.5 H+:MoVI is in accordance with the conductometric titration and indicates the formation of a metamolybdate anion.
