Zinc iodide is produced by a redox reaction between zinc metal and iodine. In the absence of acetic acid, zinc iodide is hydrolyzed to zinc hydroxide by the following equation (2): Zn(OH) 2 (s) + 2H 3 O (aq) + 2I (aq) ZnI 2 (aq) + 4H 2 O(l) Dilute acetic acid prevents observation of the white zinc hy-
15 Φεβ 2018 · Zinc and iodine, when mixed with distilled water in a test tube, will react spontaneously and exothermically to produce aqueous zinc iodide. The aqueous zinc iodide can be decomposed into its elements using a simple electrolysis apparatus.
Reaction with Sodium Hydroxide: ZnI 2 + 2NaOH → Zn(OH) 2 + 2NaI This aspect of its reactivity adds to the versatility of zinc iodide, making it a crucial ingredient in various chemical reactions and processes.
1 Σεπ 1995 · The purpose of this article is to discuss two colorful reactions not widely used by chemical educators in high schools or college chemistry laboratories: The synthesis of zinc iodide from...
This experiment involves the synthesis of a metal salt by direct reaction of a metal and a non-metal. Zinc powder is added to a solution of iodine in ethanol. An exothermic redox reaction occurs, forming zinc iodide, which can be obtained by evaporating the solvent. Zn + I 2 → ZnI 2
1 Ιουλ 2003 · The inquiry-based experiments center on alternate reaction pathways involving a second synthesis of zinc iodide and a side reaction that produces zinc hydroxide.
The reaction of zinc metal with iodine shows direct combination, decomposition, recrystallization of sublimed I2, and electrolysis. Zn(s) + I 2 (s) → No Reaction Zn(s) + I 2 (s) H 2 O→ ZnI 2 (aq)
