The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is C) K\u207a and NO\u2083\u207b<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

When potassium chloride (KCl) and silver nitrate (AgNO\u2083) are mixed in aqueous solution, a double displacement (precipitation) reaction occurs. The chemical equation is: KCl (aq)+AgNO\u2083 (aq)\u2192AgCl (s)+KNO\u2083 (aq)\\text{KCl (aq)} + \\text{AgNO\u2083 (aq)} \\rightarrow \\text{AgCl (s)} + \\text{KNO\u2083 (aq)}<\/p>\n\n\n\n

Here\u2019s a breakdown of the reaction:<\/p>\n\n\n\n

    \n
  1. Dissociation of Ionic Compounds in Water<\/strong>:
    • KCl dissociates into K\u207a and Cl\u207b ions.<\/li>
    • AgNO\u2083 dissociates into Ag\u207a and NO\u2083\u207b ions.<\/li><\/ul>Before the reaction: K\u207a\u00a0(aq),Cl\u207b\u00a0(aq),Ag\u207a\u00a0(aq),NO\u2083\u207b\u00a0(aq)\\text{K\u207a (aq)}, \\text{Cl\u207b (aq)}, \\text{Ag\u207a (aq)}, \\text{NO\u2083\u207b (aq)}<\/li>\n\n\n\n
    • Formation of a Precipitate<\/strong>: Silver chloride (AgCl) is insoluble in water and forms a precipitate: Ag\u207a\u00a0(aq)+Cl\u207b\u00a0(aq)\u2192AgCl\u00a0(s)\\text{Ag\u207a (aq)} + \\text{Cl\u207b (aq)} \\rightarrow \\text{AgCl (s)}<\/li>\n\n\n\n
    • Spectator Ions<\/strong>: The ions that do not participate in forming the precipitate<\/strong> remain in solution as spectator ions. These are K\u207a and NO\u2083\u207b, as they do not combine to form a solid or undergo any chemical change.<\/li>\n\n\n\n
    • Net Ionic Equation<\/strong>: The net ionic equation, showing only the species involved in the chemical change, is: Ag\u207a\u00a0(aq)+Cl\u207b\u00a0(aq)\u2192AgCl\u00a0(s)\\text{Ag\u207a (aq)} + \\text{Cl\u207b (aq)} \\rightarrow \\text{AgCl (s)} The K\u207a and NO\u2083\u207b ions are not included here because they do not take part in the reaction; they remain unchanged in the solution.<\/li>\n<\/ol>\n\n\n\n

      Why C is the Correct Answer:<\/h3>\n\n\n\n

      K\u207a and NO\u2083\u207b are the spectator ions since they do not react or change during the chemical process. They are present in the solution both before and after the reaction, making them the correct choice.<\/p>\n","protected":false},"excerpt":{"rendered":"
