The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n Let\u2019s go through this step by step for the reaction between hydrogen peroxide (H\u2082O\u2082)<\/strong> and magnesium sulfite (MgSO\u2083)<\/strong>.<\/p>\n\n\n\n Given Reaction:<\/strong> H2O2(aq)+MgSO3(aq)\u2192MgSO4(aq)+H2O(l)\\text{H}_2\\text{O}_2(aq) + \\text{MgSO}_3(aq) \\rightarrow \\text{MgSO}_4(aq) + \\text{H}_2\\text{O}(l)<\/p>\n\n\n\n This is a redox reaction<\/strong>. So, correct answer: Redox<\/strong>.<\/p>\n\n\n\n Start by writing all soluble compounds as dissociated ions:<\/p>\n\n\n\n Reactants:<\/strong><\/p>\n\n\n\n Products:<\/strong><\/p>\n\n\n\n Total Ionic Equation:<\/strong> H2O2(aq)+Mg2+(aq)+SO32\u2212(aq)\u2192Mg2+(aq)+SO42\u2212(aq)+H2O(l)\\text{H}_2\\text{O}_2(aq) + \\text{Mg}^{2+}(aq) + \\text{SO}_3^{2-}(aq) \\rightarrow \\text{Mg}^{2+}(aq) + \\text{SO}_4^{2-}(aq) + \\text{H}_2\\text{O}(l)<\/p>\n\n\n\n Cancel out the spectator ions. Mg\u00b2\u207a appears on both sides.<\/p>\n\n\n\n Net Ionic Equation:<\/strong> H2O2(aq)+SO32\u2212(aq)\u2192SO42\u2212(aq)+H2O(l)\\text{H}_2\\text{O}_2(aq) + \\text{SO}_3^{2-}(aq) \\rightarrow \\text{SO}_4^{2-}(aq) + \\text{H}_2\\text{O}(l)<\/p>\n\n\n\n This reaction between hydrogen peroxide and magnesium sulfite is a redox reaction. In redox (oxidation-reduction) reactions, one substance loses electrons (is oxidized) and another gains electrons (is reduced). Here, the sulfite ion (SO\u2083\u00b2\u207b) is oxidized<\/strong> to sulfate (SO\u2084\u00b2\u207b), meaning it gains oxygen or increases its oxidation state. Simultaneously, hydrogen peroxide (H\u2082O\u2082) is reduced<\/strong>, breaking down into water, which is a lower oxidation state for oxygen.<\/p>\n\n\n\n Magnesium ions (Mg\u00b2\u207a) from magnesium sulfite and magnesium sulfate do not participate in the redox process; they are spectator ions<\/strong>. Thus, they cancel out in the net ionic equation.<\/p>\n\n\n\n Hydrogen peroxide acts as a key oxidizing agent in many redox reactions because it contains an O\u2013O bond that readily breaks, allowing oxygen atoms to react. When hydrogen peroxide reacts with the sulfite ion, oxygen is transferred to the sulfite to convert it into sulfate, and H\u2082O\u2082 itself turns into H\u2082O.<\/p>\n\n\n\n The full balanced molecular reaction: H2O2(aq)+MgSO3(aq)\u2192MgSO4(aq)+H2O(l)\\text{H}_2\\text{O}_2(aq) + \\text{MgSO}_3(aq) \\rightarrow \\text{MgSO}_4(aq) + \\text{H}_2\\text{O}(l)<\/p>\n\n\n\n Total ionic equation: H2O2(aq)+Mg2+(aq)+SO32\u2212(aq)\u2192Mg2+(aq)+SO42\u2212(aq)+H2O(l)\\text{H}_2\\text{O}_2(aq) + \\text{Mg}^{2+}(aq) + \\text{SO}_3^{2-}(aq) \\rightarrow \\text{Mg}^{2+}(aq) + \\text{SO}_4^{2-}(aq) + \\text{H}_2\\text{O}(l)<\/p>\n\n\n\n Net ionic equation: H2O2(aq)+SO32\u2212(aq)\u2192SO42\u2212(aq)+H2O(l)\\text{H}_2\\text{O}_2(aq) + \\text{SO}_3^{2-}(aq) \\rightarrow \\text{SO}_4^{2-}(aq) + \\text{H}_2\\text{O}(l)<\/p>\n\n\n\n This illustrates the role of redox chemistry in transforming compounds and is commonly seen in environmental and biological processes, including disinfection and metabolism.<\/p>\n\n\n\n What kind of reaction is show below (between hydrogen peroxide and magnesium sulfite). a.
