Abstract: It is shown by interferometric measurements that the titration of Na₂MoO₄ with HClO₄, H₂SO₄, HNO₃, or HCl there is a sharp break if the ratio is 2 Mo: 3 H⁺. This indicates the formation of a metamolybdate ion. Other Mo isopolyanions do not show up on the interferometric curves. A similar break is observed with Na₂CrO₄ and bichromate formation if the ratio is 1 Cr:1 H⁺.
