7790-37-6 - Reference Information
| Introduction | Zinc iodate is a white powder or crystal. The relative density of 5.0635, the second hydrate is white crystal or powder, the relative density of 4.22325,200 deg C when the loss of 2 molecular crystal water. Zinc iodate slightly soluble in water, soluble in alkali, nitric acid, ammonia and alkali solution, thermal decomposition. |
| Use | is used as an analytical reagent and a medicinal preservative. used as analytical reagent, also used in the pharmaceutical industry |
| Application | can be used in the pharmaceutical industry, iodine starch reagent for the determination of nitrite. Zinc iodate is also used as a reagent for the analysis of free chlorine and other gasification agents. |
| synthesis method | the synthesis of Zinc iodate is to dissolve analytically pure ZnCl2 in ionic water and add analytically pure HIO3 aqueous solution to form milky white precipitate, after filtration, washing and drying, white Anhydrous Zinc iodate powder was obtained. The density was 5.08g/cm3 as measured by the heavy-bottle method. The results of differential thermal analysis show that the thermal effect of phase transition is found from the decomposition temperature of 550 ℃ at room temperature, and the decomposition product is ZnO. The second harmonic analysis of the powder sample of Zinc iodate shows that the Zinc iodate sample has a larger frequency doubling effect than the quartz powder, so it belongs to the polar crystal and has no symmetry center. |
| preparation | preparation method: obtained from the reaction of a zinc sulfate solution and Barium iodate. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water: 7.749 × 10-2/20 ℃ |
