can someone please help me balance this equation?:
potassium permanganate reacts with iron(II)sulfate and sulfuric acid to produce iron(III)sulfate and manganese(II)sulfate and potassium sulfate and water.
Try this. Check it to make sure.
10FeSO4 + 2KMnO4 + 8H2SO4 ==>5Fe2(SO4)3 + 2MnSO4 + K2SO4 + 8H2O
Certainly! Let's balance the equation step by step.
First, let's write the unbalanced chemical equation:
KMnO4 + FeSO4 + H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
Next, let's balance the equation by balancing one element at a time. We'll start with the polyatomic ions first.
Balancing the sulfate ions (SO4):
Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
Now, let's balance the potassium ions:
2K2SO4 + Fe2(SO4)3 + MnSO4 + H2O
Next, balance the iron ions:
2K2SO4 + Fe2(SO4)3 + MnSO4 + H2O
Now, let's balance the manganese ions:
2K2SO4 + Fe2(SO4)3 + MnSO4 + H2O
Lastly, let's balance the oxygen atoms, which can be balanced by adding water molecules (H2O):
2K2SO4 + Fe2(SO4)3 + MnSO4 + 8H2O
Now, let's balance the hydrogen atoms. We can do this by adding hydrogen ions (H+):
2K2SO4 + Fe2(SO4)3 + MnSO4 + 8H2O + 16H+
Finally, let's balance the charges. On the left side, the total charge is 0. On the right side, the total charge is 6+ for the iron and 2+ for the manganese. To balance the charges, we need to add 6 electrons (e-) to the left side:
2K2SO4 + Fe2(SO4)3 + MnSO4 + 8H2O + 16H+ + 6e-
The balanced equation is:
2KMnO4 + 5FeSO4 + 8H2SO4 → 5Fe2(SO4)3 + 2MnSO4 + K2SO4 + 8H2O
Sure, I can help you balance the equation. Here's the balanced equation for the reaction:
2 KMnO4 + 5 FeSO4 + 8 H2SO4 → K2SO4 + 5 Fe2(SO4)3 + 2 MnSO4 + 8 H2O
To balance the equation, follow these steps:
1. Count the number of each type of atoms on both sides of the equation.
On the left side, you have:
- 2 K
- 2 Mn
- 8 O
- 5 Fe
- 4 S
- 12 H
On the right side, you have:
- 2 K
- 2 Mn
- 8 O
- 5 Fe
- 4 S
- 12 H
2. Balance the elements one at a time, starting with the most complex molecules.
- Start by balancing the Mn atoms by placing the coefficient 2 in front of KMnO4 and MnSO4.
- You will now have:
2 KMnO4 + __ FeSO4 + __ H2SO4 → __ K2SO4 + __ Fe2(SO4)3 + 2 MnSO4 + __ H2O
3. Next, balance the Fe atoms by placing the coefficient 5 in front of FeSO4 and Fe2(SO4)3.
- You will now have:
2 KMnO4 + 5 FeSO4 + __ H2SO4 → __ K2SO4 + 5 Fe2(SO4)3 + 2 MnSO4 + __ H2O
4. Balance the S atoms by placing the coefficient 8 in front of H2SO4.
- You will now have:
2 KMnO4 + 5 FeSO4 + 8 H2SO4 → __ K2SO4 + 5 Fe2(SO4)3 + 2 MnSO4 + __ H2O
5. Finally, balance the H atoms by placing the coefficient 8 in front of H2O.
- You will now have the final balanced equation:
2 KMnO4 + 5 FeSO4 + 8 H2SO4 → K2SO4 + 5 Fe2(SO4)3 + 2 MnSO4 + 8 H2O
Make sure to double-check the coefficients to ensure that the number of atoms for each element is balanced on both sides of the equation.
