Step 1 of 2

Given data: the following ions: NH4+,Fe3+,NO3−,IO3−

 

Find: write the empirical formula for at least four ionic compounds

Explanation:

The empirical formulas will be based on the charges of the ions, ensuring that the overall charge of the compound is neutral.

 

Step 2 of 2

let’s consider various combinations of the provided ions to form ionic compounds.

 

  1. Ammonium Nitrate:
    • (NH₄)⁺ (Ammonium) and (NO₃)⁻ (Nitrate) ions combine to form ₄₃NH₄NO₃

 

  1. Iron(III) Nitrate:
    • Fe³⁺ (Iron(III)) and (NO₃)⁻ (Nitrate) ions combine to form ₃₃Fe(NO₃)₃
  2. Ammonium Iodate:
    • (NH₄)⁺ (Ammonium) and (IO₃)⁻ (Iodate) ions combine to form ₄₃(NH₄)IO₃

 

  1. Iron(III) Iodate:
    • Fe³⁺ (Iron(III)) and (IO₃)⁻ (Iodate) ions combine to form ₃₃Fe(IO₃)₃

Explanation:

Hence, using the four ions we have calculated the ionic compounds.

 

Final solution

These formulas are based on the principle of charge balance in ionic compounds. The charges on the cations and anions are combined in such a way that the overall charge of the compound is electrically neutral.

Therefore, the four ions are:

  • NH₄NO₃
  • Fe(NO₃)₃
  • (NH₄)IO₃
  • Fe(IO₃)₃
