Magnesium selenates

The solubility of MgSe04-6H20(cr) in water at 298.15 K has been measured in many papers. The selected solubility  [Pg.397]

A phase diagram and related information are available for the system MgSe04-H2Se04-H20 at 303.15 K in [44FUR/KIN] MgSe04-(NH4)2Se04-H20 at [Pg.397]

Tellurium has been separated from Se after sintering the sample with Eschka mixture (1 part by weight of Na2COj + 2 parts of MgO) for 40 min at 800°C [2]. When the sinter is leached with water, the readily soluble magnesium selenate passes into solution while sparingly soluble magnesium tellurate remains in the precipitate. [Pg.412]

Gelbach and King [42GEL/K1N] prepared their specimen of Ag2Se04(s) by slow precipitation from 10% silver nitrate and magnesium selenate solutions. The solubility in six solutions of selenic acid in the concentration range from 0.00 to 0.12 M was determined. Equilibrium was approached from under- as well as supersaturation. The solubility in water was found to be 2.42 x 10 M. No solubility product was calculated from the data. This has been done here with log K° = 1.75 for the protonation constant... [Pg.305]
