WebSolubility table. The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams per 100 millilitres of water (g/100 mL), unless shown otherwise. The substances are listed in alphabetical order. Molybdate (usually in the form of potassium molybdate) is also used in the analytical colorimetric testing for the concentration of silica in solution, called the molybdenum blue method. Additionally, it is used in the colorimetric determination of phosphate quantity in association with the dye malachite … Meer weergeven 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 … Meer weergeven The smaller anions, MoO 4 and Mo 2O 7 feature tetrahedral centres. In MoO 4 the four oxygens are equivalent as in sulfate and chromate, with equal bond lengths and angles. Mo 2O 7 can be considered to be two tetrahedra sharing a corner, i.e. with a single … Meer weergeven Catalysis Molybdates are widely used in catalysis.
