Write a balanced equation for the reaction between aqueous magnesium nitrate and aqueous potassium hydroxide to form solid magnesium hydroxide and aqueous potassium nitrate.<\/p>\n\n\n\n

The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The balanced chemical equation for the reaction between aqueous magnesium nitrate (Mg(NO\u2083)\u2082) and aqueous potassium hydroxide (KOH) to form solid magnesium hydroxide (Mg(OH)\u2082) and aqueous potassium nitrate (KNO\u2083) is: Mg(NO\u2083)\u2082 (aq)+2KOH (aq)\u2192Mg(OH)\u2082 (s)+2KNO\u2083 (aq)\\text{Mg(NO\u2083)\u2082 (aq)} + 2\\text{KOH (aq)} \\rightarrow \\text{Mg(OH)\u2082 (s)} + 2\\text{KNO\u2083 (aq)}<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n
    \n
  1. Identifying the Reactants and Products:<\/strong>\n
      \n
    • Magnesium nitrate (Mg(NO\u2083)\u2082) is a soluble salt, meaning it dissociates in water into magnesium ions (Mg\u00b2\u207a) and nitrate ions (NO\u2083\u207b).<\/li>\n\n\n\n
    • Potassium hydroxide (KOH) is a strong base, also soluble in water, and dissociates into potassium ions (K\u207a) and hydroxide ions (OH\u207b).<\/li>\n\n\n\n
    • Magnesium hydroxide (Mg(OH)\u2082) is only slightly soluble in water and forms a precipitate when the reaction takes place.<\/li>\n\n\n\n
    • Potassium nitrate (KNO\u2083) is a soluble salt, and it dissociates in water into potassium ions (K\u207a) and nitrate ions (NO\u2083\u207b).<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Writing the Ionic Equation:<\/strong>
      In solution, the ions involved are:\n
        \n
      • Magnesium nitrate<\/strong> dissociates into Mg\u00b2\u207a and 2NO\u2083\u207b.<\/li>\n\n\n\n
      • Potassium hydroxide<\/strong> dissociates into K\u207a and OH\u207b.
        The magnesium hydroxide<\/strong> formed is insoluble and will precipitate as a solid, while potassium nitrate<\/strong> remains dissolved in solution as K\u207a and NO\u2083\u207b.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Balancing the Equation:<\/strong>\n
          \n
        • The magnesium ion (Mg\u00b2\u207a) from magnesium nitrate combines with two hydroxide ions (OH\u207b) to form magnesium hydroxide (Mg(OH)\u2082), which precipitates out of solution.<\/li>\n\n\n\n
        • For every mole of magnesium nitrate, two moles of potassium hydroxide are needed to supply enough hydroxide ions (OH\u207b) for the formation of magnesium hydroxide.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Final Balanced Equation:<\/strong>
          • Since there are two potassium ions (K\u207a) from two KOH molecules and two nitrate ions (NO\u2083\u207b) from one magnesium nitrate molecule, the equation is balanced as follows:<\/li><\/ul>Mg(NO\u2083)\u2082\u00a0(aq)+2KOH\u00a0(aq)\u2192Mg(OH)\u2082\u00a0(s)+2KNO\u2083\u00a0(aq)\\text{Mg(NO\u2083)\u2082 (aq)} + 2\\text{KOH (aq)} \\rightarrow \\text{Mg(OH)\u2082 (s)} + 2\\text{KNO\u2083 (aq)}<\/li>\n<\/ol>\n\n\n\n

            In conclusion, the equation is properly balanced with 1 magnesium atom, 2 potassium atoms, 2 nitrate ions, and 2 hydroxide ions on both sides of the equation.<\/p>\n","protected":false},"excerpt":{"rendered":"
