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.

Table \(\PageIndex{2}\) lists the ion names and ion formulas of the most common polyatomic ions. For example, \(\ce{NO3^{−}}\) is the nitrate ion; it has one nitrogen atom and three oxygen atoms and an overall 1− charge.
25 Σεπ 2022 · Writing Formulas for Ionic Compounds Containing Polyatomic Ions. Writing a formula for ionic compounds containing polyatomic ions also involves the same steps as for a binary ionic compound. Write the symbol and charge of the cation followed by the symbol and charge of the anion. Example 5.5.4: Calcium Nitrate.
