Final answer:

The empirical formulas for ionic compounds between the ions Pb4+, SO4^2-, ClO-, and Fe3+ are formed by combining these ions in ratios that balance the positive and negative charges, resulting in electrically neutral compounds like Pb(SO4)2, Fe(SO4)3, Pb(ClO)4, and Fe(ClO)3.

Step-by-step explanation:

The empirical formulas for four ionic compounds that could be formed from the ions mentioned (Pb4+, SO42-, ClO-, Fe3+) would be based on the charge balance between the cations and anions. To achieve electrical neutrality, the total positive charge must equal the total negative charge.


  • Pb(SO4)2: Lead(IV) sulfate

  • Fe(SO4)3: Iron(III) sulfate

  • Pb(ClO)4: Lead(IV) hypochlorite

  • Fe(ClO)3: Iron(III) hypochlorite

Each compound listed above has a cation and a polyatomic ion combining in ratios that satisfy the charge balance required for the formation of an electrically neutral compound.
