Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understanding the Permanganate Ion
- The permanganate ion is $$MnO_{4}^{-}
- It has a charge of - 1 - We need to balance the charges when forming ionic compounds with different cations
Step 3:: Compound with Potassium (K+)
- Formula: $$KMnO_{4}
- Potassium ion has a charge of + 1 - Name: Potassium permanganate
Step 4:: Compound with Calcium (Ca^2 +)
- Formula: $$Ca(MnO_{4})_{2}
- Calcium ion has a charge of + 2 - Name: Calcium permanganate
Step 5:: Compound with Iron(2$) (Fe^3 +)
- Formula: $$Fe(MnO_{4})_{3}
- Iron(III) ion has a charge of + 3 - Name: Iron(III) permanganate
Final Answer
1. KMnO_{4} (Potassium permanganate) 2. Ca(MnO_{4})_{2} (Calcium permanganate) 3. Fe(MnO_{4})_{3} (Iron(III) permanganate)
