1. The molybdate ( VI ) anion is tetrahedral. 2. The laboratory synthesis entails the acidification of aqueous solutions of sodium molybdate with perchloric acid: 3. Thus molybdenum ( VI ) does not form, but forms the tetrahedral molybdate anion,. 4. "' Powellite "'is a calcium molybdate mineral with formula CaMoO 4. 5. "' Wulfenite "'is a lead molybdate mineral with the formula O 4. 6. Powellite ( calcium molybdate ) and scheelite ( calcium tungstate ) fluoresce intrinsically in yellow and blue, respectively. 7. The reaction it catalyzes is as follows : adenylyl-molybdopterin + molybdate \ rightarrow molybdenum cofactor + AMP. 8. In aqueous solutions of acidified molybdate salts low concentration molecular O 3 Mo?H 2 O has been characterised spectroscopically. 9. The "'molybdovanadate reagent "'is a solution containing both the molybdate and vanadate ions. 10. This compound is generated directly from molybdate held on alumina within the generator ( see this topic for detail ).
