Question

Which of the three ionic compounds has the greatest amount of ion-ion forces? Answer Choices:

-Ammonium nitrate (NH₄NO₃),
-Potassium bromide (KBr),
-Calcium carbonate (CaCO₃),
-They all have the same amount of ion-ion forces.

Answer 1

Calcium carbonate (CaCO₃) has the greatest amount of ion-ion forces among the three ionic compounds mentioned. The correct answer is option: Calcium carbonate (CaCO₃)

Step-by-step explanation:

• The compound with the greatest amount of ion-ion forces among the three ionic compounds mentioned (ammonium nitrate (NH₄NO₃), potassium bromide (KBr), and calcium carbonate (CaCO₃)) is calcium carbonate (CaCO₃).
• This is because calcium carbonate has a higher charge on its ions compared to the other compounds. The calcium ion (Ca²⁺) has a higher charge than the ammonium ion (NH4+) and the potassium ion (K+), while the carbonate ion (CO₃²⁻) has a higher charge than the bromide ion (Br-) in potassium bromide.
• Therefore, calcium carbonate experiences stronger ion-ion forces due to the higher charges on its ions, making it the compound with the greatest amount of ion-ion forces among the three.
