Indium Molybdate, In2(Mo04)3.2H20, is obtained as a white voluminous mass when ammonium paramolybdate solution is added to solutions of indium salts. [Pg.144]

Tetramolybdates or metamolybdates, M20-4Mo03- H20, are formed from concentrated solutions of alkali molybdates treated with 1.5 mols per mol of hydrochloric acid. Octamolybdates are obtained similarly from solutions containing 1.75 mols per mol of hydrochloric acid or by adding the calculated amount of M0O3 to ammonium paramolybdate solution. Both the tetra- and octa-molybdates are derived from the ion [Mo8026]4. ... [Pg.951]

Note Commercial ammonium molybdate has the formula (NH4)6Mo7024. 4H20 (a paramolybdate) and not (NH4)2Mo04 but the ion Mo04 is employed in the equations for purposes of simplicity. These ions may exist under the experimental conditions of the reaction. [Pg.356]

Cadmium Molybdates.— The normal salt CdMoO is obtained as a heaY-y white precipitate when a soluble cadmium salt is added to a solution of an alkali molybdate or paramolybdate. The precipitate is readily soluble in mineral acids, ammonium hydroxide, or aqueous potassium cyanide. By fusing together sodium molybdate (2 parts), cadmium chloride (7 parts), and sodium chloride (6 parts), the salt may be obtained as lustrous yellow crystals. ... [Pg.141]

Since ammonium molybdate already gives a precipitate with Ba itself in the control experiment, it is not possible to establish whether tricomplex flocculation occurs in the combination colloid amphoion -f- Ba -f paramolybdate. [Pg.424]
