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
31 Ιουλ 2021 · Several important chemical reactions of alcohols involve only the oxygen-hydrogen bond and leave the carbon-oxygen bond intact. An important example is salt formation with acids and bases. Alcohols, like water, are both weak bases and weak acids.
barium iodide reacts with zinc sulfate to produce zinc iodide. Quantitatively, zinc iodide can be synthesized by the double replacement reaction with close to a 100% yield 1 (Table 1).
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...
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.
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.
9 Απρ 2018 · These NBO-derived charge maps provide a rationale for remote iodide anion quenching in reactions that resemble the S N 1′ and S N 2′ processes in the gas phase. The endergonicity of the reactions of addition of iodide was slightly decreased by solvation (Table 2, entries 7 and 8).
