The name of the ionic compound (NH4)3PO4 is<\/p>\n\n\n\n

a) ammonium phosphate<\/p>\n\n\n\n

b) nitrogen hydrogen phosphate<\/p>\n\n\n\n

c) tetrammonium phosphate<\/p>\n\n\n\n

d) ammonia posphide<\/p>\n\n\n\n

e) triammonium phosphate<\/p>\n\n\n\n

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

The correct answer is:<\/p>\n\n\n\n

a) ammonium phosphate<\/strong><\/p>\n\n\n\n

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

The given chemical formula (NH\u2084)\u2083PO\u2084<\/strong> consists of two ions:<\/p>\n\n\n\n

    \n
  1. Ammonium ion (NH\u2084\u207a)<\/strong><\/li>\n\n\n\n
  2. Phosphate ion (PO\u2084\u00b3\u207b)<\/strong><\/li>\n<\/ol>\n\n\n\n

    To systematically determine the name of the compound, follow these steps:<\/p>\n\n\n\n

    Step 1: Identify the Cation and Anion<\/strong><\/h4>\n\n\n\n
      \n
    • NH\u2084\u207a (Ammonium ion)<\/strong>: A polyatomic ion with a +1 charge.<\/li>\n\n\n\n
    • PO\u2084\u00b3\u207b (Phosphate ion)<\/strong>: A polyatomic ion with a -3 charge.<\/li>\n<\/ul>\n\n\n\n

      Step 2: Charge Balancing<\/strong><\/h4>\n\n\n\n

      Each ammonium ion (NH\u2084\u207a) carries a +1 charge, and the phosphate ion (PO\u2084\u00b3\u207b) has a -3 charge. To balance the charges, three NH\u2084\u207a ions are required for every PO\u2084\u00b3\u207b ion:<\/p>\n\n\n\n

      [
      (3 \\times +1) + (-3) = 0
      ]<\/p>\n\n\n\n

      This ensures a neutral compound, leading to the formula (NH\u2084)\u2083PO\u2084<\/strong>.<\/p>\n\n\n\n

      Step 3: Naming the Compound<\/strong><\/h4>\n\n\n\n
        \n
      • The NH\u2084\u207a<\/strong> ion is named ammonium<\/strong>.<\/li>\n\n\n\n
      • The PO\u2084\u00b3\u207b<\/strong> ion is named phosphate<\/strong>.<\/li>\n<\/ul>\n\n\n\n

        Since this is an ionic compound<\/strong>, no prefixes (such as mono-, di-, tri-) are needed. The name follows the standard naming convention of ionic compounds:<\/p>\n\n\n\n

        Cation name + Anion name = Ammonium phosphate<\/strong><\/p>\n\n\n\n

        Why Other Options Are Incorrect:<\/strong><\/h4>\n\n\n\n
          \n
        • b) Nitrogen hydrogen phosphate<\/strong> \u2192 This does not correctly describe the ionic components.<\/li>\n\n\n\n
        • c) Tetrammonium phosphate<\/strong> \u2192 Incorrect prefix; ammonium ions are not counted with prefixes.<\/li>\n\n\n\n
        • d) Ammonia phosphide<\/strong> \u2192 Ammonia (NH\u2083) is a molecule, not an ion, and phosphide (P\u00b3\u207b) is different from phosphate (PO\u2084\u00b3\u207b).<\/li>\n\n\n\n
        • e) Triammonium phosphate<\/strong> \u2192 “Triammonium” is not a standard nomenclature term in ionic chemistry.<\/li>\n<\/ul>\n\n\n\n

          Thus, the correct name for (NH\u2084)\u2083PO\u2084<\/strong> is ammonium phosphate<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
