Question
### Total Ionic Equation The equation shown is as follows: \[ \text{Cu}^{2+}(\text{aq}) + \text{SO}_4^{2-}(\text{aq}) + \text{Mg}(\text{s}) \rightarrow \text{Mg}^{2+}(\text{s}) + \text{SO}_4^{2-}(\text{aq}) + \text{Cu}^{2+}(\text{aq}) \] This equation is labeled as "Incorrect." **Explanation:** - **Reactants:** - Copper ions (\(\text{Cu}^{2+}\)) in aqueous solution. - Sulfate ions (\(\text{SO}_4^{2-}\)) in aqueous solution. - Solid magnesium (\(\text{Mg(s)}\)). - **Products:** - Magnesium ions (\(\text{Mg}^{2+}\)) labeled incorrectly as solid (\(\text{s}\)) instead of being expected in aqueous form. - Sulfate ions (\(\text{SO}_4^{2-}\)) in aqueous solution. - Copper ions (\(\text{Cu}^{2+}\)) in aqueous solution. **Note:** - The total ionic equation should represent all strong electrolytes as ions in solution. In this case, the incorrect part is representing \(\text{Mg}^{2+}\) as solid, which should be in aqueous form (\(\text{aq}\)) after displacement of copper ions. The given form contradicts the typical displacement reaction pattern where solid magnesium would displace copper ions from the solution to form \(\text{Mg}^{2+}(\text{aq})\).
