Explanation<\/strong><\/h3>\n\n\n\n

When two aqueous ionic compounds are mixed and a solid forms, this is known as a precipitation reaction<\/strong>. The question involves Silver Nitrate (AgNO\u2083)<\/strong> and Sodium Phosphate (Na\u2083PO\u2084)<\/strong>, both of which are soluble in water and dissociate into their respective ions:<\/p>\n\n\n\n

    \n
  • AgNO\u2083 \u2192 Ag\u207a + NO\u2083\u207b<\/li>\n\n\n\n
  • Na\u2083PO\u2084 \u2192 3Na\u207a + PO\u2084\u00b3\u207b<\/li>\n<\/ul>\n\n\n\n

    When Ag\u207a<\/strong> (silver ion) and PO\u2084\u00b3\u207b<\/strong> (phosphate ion) come together in solution, they form an insoluble salt<\/strong>, silver phosphate (Ag\u2083PO\u2084)<\/strong>, which precipitates out as a yellow solid<\/strong>. The net ionic equation includes only the ions that participate in forming the precipitate<\/strong>, excluding spectator ions like Na\u207a and NO\u2083\u207b, which do not change during the reaction.<\/p>\n\n\n\n

    The correct net ionic equation<\/strong> shows the combination of 3 Ag\u207a ions<\/strong> and 1 PO\u2084\u00b3\u207b ion<\/strong> to form solid Ag\u2083PO\u2084<\/strong>:<\/p>\n\n\n\n

    \n

    3Ag\u207a + PO\u2084\u00b3\u207b \u2192 Ag\u2083PO\u2084(s)<\/strong><\/p>\n<\/blockquote>\n\n\n\n

    Let\u2019s analyze the incorrect options:<\/p>\n\n\n\n

      \n
    • \u274c Ag\u207a + PO\u2084\u00b3\u207b \u2192 Ag\u2083PO\u2084(s):<\/strong> Incorrect stoichiometry; 3 Ag\u207a ions are needed to balance the -3 charge of PO\u2084\u00b3\u207b.<\/li>\n\n\n\n
    • \u274c Ag\u207a + NO\u2083\u207b + Na\u207a + PO\u2084\u00b3\u207b \u2192 Ag\u2083PO\u2084(s):<\/strong> Includes all ions; not a net ionic equation.<\/li>\n\n\n\n
    • \u274c AgNO\u2083 + Na\u2083PO\u2084 \u2192 Ag\u2083PO\u2084(s):<\/strong> This is the molecular equation<\/strong>, not the net ionic<\/strong> one.<\/li>\n<\/ul>\n\n\n\n

      The net ionic equation strips the reaction down to its essence<\/strong>, showing only the species that actually form the precipitate<\/strong>. This not only simplifies the chemistry but also emphasizes the key reaction: the formation of the insoluble Ag\u2083PO\u2084<\/strong> from free ions in solution.<\/p>\n\n\n\n
