The results indicated that three salts in water belonged to strong electrolyte and their conductivity varied very much. The limiting molar conductivity of FDPMg, FDPNa and MgSO4 at 25℃ calculated by linear fit was 0.02007, 0.03205, 0.02633 S·m2·mol-1,respectively. When concentration was 1×10-3 mol·dm-3(equal to blood concentration), the molecule proportion of the three salts in water was: FDPNa (8.6%) <MgSO4(12.9%)<FDPMg(18.9%); the molecule proportion of the three salts in plasma has not been confirmed at present.展开更多
