The appearance of zinc iodide is white or nearly white granular powder, which gradually turns brown in the air due to the release of iodine and has deliquation. The melting point is 446℃, the boiling point is about 624℃(and decomposition), and the relative density is 4.736(25℃). Soluble in water, ethanol, ether, ammonia, sodium hydroxide and ammonium carbonate solutions. Its aqueous solution is acidic to litmus, with a pHChemicalbook of about 5. Keep away from moisture and in an airtight container away from light. A reagent for the analysis of nitrite, free chlorine, and other oxidizing agents, used in photography and medicine as a preservative and local astringent. Preparation method: The zinc sulfate solution interacts with the barium iodide solution, the barium sulfate is filtered and precipitated, and the filtrate is evaporated to crystallize it, or the direct combination of zinc and iodine is prepared.
