In chemistry, a molybdate is a compound containing an oxoanion with molybdenum in its highest oxidation state of 6: O −Mo(=O)2−O . Molybdenum can form a very large range of such oxoanions, which can be discrete structures or polymeric extended structures, although the latter are only … Meer weergeven Examples of molybdate oxoanions are: • MoO 4, in e.g. Na2MoO4 and the mineral powellite, CaMoO4; • Mo 2O 7, as hydrated ammonium dimolybdate. The anhydrous tetrabutylammonium salt of Mo 2O 7 is also known; Meer weergeven When MoO3, molybdenum trioxide is dissolved in alkali solution the simple MoO2−4 anion is produced: As the pH is lowered, condensations ensue, with loss of water and the formation of Mo–O–Mo linkages.
