30 Ιουν 2023 · The reaction between persulfate ions (peroxodisulfate ions), S 2 O 8 2-, and iodide ions in solution can be catalyzed using either iron(II) or iron(III) ions. The overall equation for the reaction is: \[ S_2O_8^{2-} + 2I^- \rightarrow 2SO_4^{2-}+ I_2 \label{2} \] For the sake of argument, we'll take the catalyst to be iron(II) ions.
19 Σεπ 2022 · The charge of the metal ion is determined from the formula of the compound and the charge of the anion. For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+ (see [link]), and the two corresponding compound formulas are FeCl 2 and FeCl 3.
25 Σεπ 2022 · This section will teach you how to find the correct ratio of ions, so that you can write a correct formula. If you know the name of a binary ionic compound, you can write its chemical formula. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge.
