개요
Radium sulfate has the molecular formula of RaSO4 and the molecular weight of 322.0626 g/mol. It can be prepared by dissolving radium oxide in sodium sulfate solution:RaO+Na2SO4+H2O RaSO4+NaOH
Radium sulfate is insoluble in water with a solubility product of 3.66×10-11. The solubility of radium sulfate would appear as at least 100-fold less than barium sulfate. Thus, it is the most insoluble sulfate known. Its CAS Number is 7446-16-4. It appears as white crystals. Since radium is a decay product in the 238U series which then allows radon to accumulate in household basements, it is RaSO4 that has received some attention in the scientific literature.
화학적 성질
white, rhomb crystal(s) when pure, else colored yellow, orange, pink; radioactive [HAW93] [CRC10]용도
Radium sulfate (RaSO4) is the most insoluble sulfate known in chemistry and is created when radium combines with a sulfate ion (Ra + H2SO4 → RaSO4 + H2↑).황산라디움 준비 용품 및 원자재
