Bisiodic acid cadmium salt - References
| solubility in water (g/100ml) | dissolved grams per 100ml of water: 9.7 × 10-2/20 ℃ |
| use | used as analytical reagent and oxidant. It is obtained by the interaction of cadmium nitrate and iodic acid. |
| production method | mixing cadmium salt solution with sodium iodate solution to precipitate transparent rhombus crystals of Cd(IO3)2 · H2O, and dehydrating the salt under reduced pressure to obtain cadmium iodate crystals. Or dissolve cadmium hydroxide in iodic acid solution, evaporate and crystallize. |
