When mixed, solutions of silver nitrate, AgNO 3<\/sub>, and sodium phosphate, Na 3<\/sub>PO 4<\/sub>, will form a precipitate of silver phosphate, Ag 3<\/sub>PO 4<\/sub>.

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

Incorrect Statement:<\/h3>\n\n\n\n

“3 moles of Ag\u2083PO\u2084 should form when 3 moles of Na\u2083PO\u2084 react with sufficient AgNO\u2083.”<\/strong><\/p>\n\n\n\n

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

To determine why this statement is incorrect, we need to analyze the balanced chemical equation:<\/p>\n\n\n\n

[
3AgNO\u2083(aq) + Na\u2083PO\u2084(aq) \\rightarrow Ag\u2083PO\u2084(s) + 3NaNO\u2083(aq)
]<\/p>\n\n\n\n

This equation shows that 1 mole of Na\u2083PO\u2084 reacts with 3 moles of AgNO\u2083<\/strong> to form 1 mole of Ag\u2083PO\u2084<\/strong> and 3 moles of NaNO\u2083<\/strong>.<\/p>\n\n\n\n

Now, let’s apply this stoichiometric relationship to the incorrect statement:<\/p>\n\n\n\n

    \n
  • The statement suggests that 3 moles of Na\u2083PO\u2084 would produce 3 moles of Ag\u2083PO\u2084.<\/li>\n\n\n\n
  • According to the balanced equation, 1 mole of Na\u2083PO\u2084 forms 1 mole of Ag\u2083PO\u2084<\/strong>, so 3 moles of Na\u2083PO\u2084 should indeed produce 3 moles of Ag\u2083PO\u2084.<\/li>\n<\/ul>\n\n\n\n

    At first glance, this statement seems correct<\/strong>, but the mistake lies in not checking if there is sufficient AgNO\u2083<\/strong>.<\/p>\n\n\n\n

    For 3 moles of Na\u2083PO\u2084 to fully react, we need:<\/p>\n\n\n\n

    [
    3 \\times 3 = 9 \\text{ moles of } AgNO\u2083
    ]<\/p>\n\n\n\n

    However, the statement does not specify whether there is enough AgNO\u2083. It assumes Ag\u2083PO\u2084 will form regardless of the limiting reagent, which could be misleading. If there is insufficient AgNO\u2083, less than 3 moles of Ag\u2083PO\u2084 would actually form<\/strong>.<\/p>\n\n\n\n

    Thus, the statement is incorrect because it does not account for the need for 9 moles of AgNO\u2083 as a reactant<\/strong> for 3 moles of Na\u2083PO\u2084.<\/p>\n","protected":false},"excerpt":{"rendered":"
