 Write the name for Ba3(PO4)2<\/p>\n\n\n\n

A) barium (III) phosphite<\/p>\n\n\n\n

B) barium (II) phosphite<\/p>\n\n\n\n

C) barium phosphate<\/p>\n\n\n\n

D) tribarium phosphorustetraoxide<\/p>\n\n\n\n

E) barium phosphite<\/p>\n\n\n\n

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

The correct answer is:
C) Barium Phosphate<\/strong><\/p>\n\n\n\n

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

To determine the name of Ba\u2083(PO\u2084)\u2082<\/strong>, we need to follow the systematic rules for naming ionic compounds.<\/p>\n\n\n\n

Step 1: Identify the Cation (Ba\u00b3\u207a)<\/strong><\/h4>\n\n\n\n
    \n
  • The first part of the formula is Ba<\/strong>, which represents Barium<\/strong>.<\/li>\n\n\n\n
  • Barium is an alkaline earth metal in Group 2<\/strong> of the periodic table, meaning it always has a +2 charge (Ba\u00b2\u207a).<\/strong><\/li>\n<\/ul>\n\n\n\n

    Step 2: Identify the Anion (PO\u2084\u00b3\u207b)<\/strong><\/h4>\n\n\n\n
      \n
    • The second part of the formula is (PO\u2084)\u2082<\/strong>, which is the phosphate ion (PO\u2084\u00b3\u207b).<\/strong><\/li>\n\n\n\n
    • Phosphate is a polyatomic ion with a charge of -3<\/strong>.<\/li>\n<\/ul>\n\n\n\n

      Step 3: Balance the Charges<\/strong><\/h4>\n\n\n\n
        \n
      • The total charge of the compound must be neutral<\/strong>.<\/li>\n\n\n\n
      • Since barium has a +2 charge (Ba\u00b2\u207a)<\/strong> and phosphate has a -3 charge (PO\u2084\u00b3\u207b)<\/strong>, we need 3 Ba\u00b2\u207a ions<\/strong> to balance with 2 PO\u2084\u00b3\u207b ions<\/strong>, creating the formula Ba\u2083(PO\u2084)\u2082<\/strong>.<\/li>\n<\/ul>\n\n\n\n

        Step 4: Naming the Compound<\/strong><\/h4>\n\n\n\n
          \n
        • The cation (Ba\u00b2\u207a) name is simply “Barium”<\/strong> because it is from Group 2, and Group 2 metals do not require a Roman numeral.<\/li>\n\n\n\n
        • The anion (PO\u2084\u00b3\u207b) is “Phosphate”<\/strong> (not “Phosphite,” which is PO\u2083\u00b3\u207b).<\/li>\n\n\n\n
        • When combining the two, the name remains Barium Phosphate<\/strong>.<\/li>\n<\/ul>\n\n\n\n

          Why the Other Options Are Incorrect:<\/strong><\/h3>\n\n\n\n
            \n
          • A) Barium (III) phosphite<\/strong> \u2013 Incorrect because barium does not form a +3 charge, and “phosphite” is PO\u2083\u00b3\u207b, not PO\u2084\u00b3\u207b.<\/li>\n\n\n\n
          • B) Barium (II) phosphite<\/strong> \u2013 Incorrect because “phosphite” (PO\u2083\u00b3\u207b) is the wrong anion.<\/li>\n\n\n\n
          • D) Tribarium phosphorus tetraoxide<\/strong> \u2013 Incorrect because ionic compounds do not use prefixes like “tri-” or “tetra-” for naming.<\/li>\n\n\n\n
          • E) Barium phosphite<\/strong> \u2013 Incorrect because “phosphite” (PO\u2083\u00b3\u207b) is the wrong anion.<\/li>\n<\/ul>\n\n\n\n

            Thus, the correct name for Ba\u2083(PO\u2084)\u2082<\/strong> is Barium Phosphate<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
