Question

6 multiple choice 1 point pt(po₄) platinum phosphate platinum (iii) phosphate platinum phosphate (iii)

Explanation:

• For ionic compounds with transition metals (like platinum), we need to indicate the oxidation state of the metal in Roman numerals.
• The phosphate ion (\(PO_{4}^{3 -}\)) has a charge of - 3. Let the oxidation state of platinum (\(Pt\)) be \(x\). In a neutral compound \(Pt(PO_{4})\), using the charge balance rule \(x+(-3)=0\), so \(x = + 3\).
• The naming convention for ionic compounds is: metal name (oxidation state in Roman numerals) + non - metal (or polyatomic ion) name.

Answer:

Platinum (III) Phosphate
