• 説明

  Magnesium selenate has the molecular formula of MgSeO4 and the molecular weight of 167.2566 g/mol. It can be prepared by reacting sodium selenate with magnesium chloride in solution:
  MgCl2(aq)+ Na2SeO4(aq) ? MgSeO4+ 2NaCl(aq)
  It is soluble in water and the solution must be evaporated to obtain crystals of the hexahydrate, MgSeO4·6H2O. Its molecular weight is 275.3641 g/mol. It is a white, monoclinic crystal with a density of 1.928 g/cm3. Its CAS number is 13446-58-1 and it is soluble in water (55.52 g/100 ml at 60°C). The anhydrate is stable upon heating to 1338°C the heat of formation, △H_f°= —968.5 kJ/mol.
