Sodium molybdate has the advantage in that the dosing of lower ppm's of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition as sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a ...
In chemistry, a molybdate is a compound containing an oxyanion with molybdenum in its highest oxidation state of +6: O − −Mo(=O) 2 −O −. Molybdenum can form a very large range of such oxyanions , which can be discrete structures or polymeric extended structures, although the latter are only found in the solid state.
In this case, sacrificial anodes work as part of a galvanic couple, promoting corrosion of the anode, while protecting the cathode metal. In other cases, such as mixed metals in piping (for example, copper, cast iron and other cast metals), galvanic corrosion will contribute to accelerated corrosion of parts of the system.
In February 2006, an M44 device killed a man's dog in Utah, as the dog and owner were walking through public land. The man was also affected by the cyanide in the device, and sought compensation from the US Department of Agriculture's Wildlife Service, along with the Utah Department of Food and Agriculture.

Iron(II) molybdate is prepared by the reaction of iron(II) chloride or iron(II) sulfate [3] and sodium molybdate. Na 2 MoO 4 + FeSO 4 → Na 2 SO 4 + FeMoO 4.
The Saint Miguel Cattle Dog (Portuguese: cão fila de São Miguel [ˈkɐ̃w ˈfilɐ ðɨ ˈsɐ̃w miˈɣɛl], literally 'catch dog of São Miguel') is a dog breed of mastiff type originating on São Miguel Island in the Azores, an island chain which is one of the autonomous regions of Portugal.
