How do you write the balanced chemical equation for the addition of aqueous potassium fluoride to aqueous copper(II) sulfate? please explain this as a step by step process.
Convert names to chemical formulas.
KF(aq) + CuSO4(aq) ==> copper(II) fluoride + potassium sulfate.
KF(aq) + CuSO4(aq) ==> CuF2 + K2SO4
Then by trial and error balance.(remember to balance you may change ONLY the coefficients--you may NOT change the subscripts) The easy way is to look at the right and see you have 2F so make that 2 on the left with
2KF(aq) + CuSO4(aq) ==> CuF2 + K2SO4
I think that does it but ALWAYS check the final to see it is right. You will ALWAYS know if you are right or not.
I see 2 K on the left and 2 on the right.
I see 2 F on the left and 2 on the right. I see 1 Cu on left and right and one SO4 on the left and right. So the equation is balanced.
To write the balanced chemical equation for the addition of aqueous potassium fluoride to aqueous copper(II) sulfate, you need to follow a step-by-step process. Here's how you can do it:
Step 1: Identify the chemical formulas of the reactants and products involved in the reaction.
- Aqueous potassium fluoride: KF (potassium fluoride) + H2O (water)
- Aqueous copper(II) sulfate: CuSO4 (copper(II) sulfate) + H2O (water)
Step 2: Write the unbalanced equation without coefficients by just combining the formulas of the reactants and products.
- KF(aq) + CuSO4(aq) → K2SO4(aq) + CuF2(aq) + H2O(l)
Step 3: Balance the equation by adding coefficients to make sure there is an equal number of each element on both sides of the equation.
- KF(aq) + CuSO4(aq) → K2SO4(aq) + CuF2(aq) + H2O(l)
Step 4: Count the atoms of each element on both sides of the equation and adjust the coefficients accordingly. Start with the elements that appear in the fewest compounds.
- K: 1 on the left, 2 on the right (add a coefficient of 2 in front of KF on the left side)
- F: 1 on the left, 2 on the right (add a coefficient of 2 in front of CuF2 on the right side)
- S: 1 on the left, 1 on the right (equation is already balanced for S)
- O: 4 on the left, 4 on the right (equation is already balanced for O)
- H: 2 on the right (add a coefficient of 2 in front of H2O on the right side)
Step 5: Check that all elements are balanced by verifying that the number of atoms of each element is the same on both sides of the equation.
- K: 2 on the left, 2 on the right
- F: 2 on the left, 2 on the right
- S: 1 on the left, 1 on the right
- O: 4 on the left, 4 on the right
- H: 2 on the right
Step 6: Write the final balanced equation.
- 2KF(aq) + CuSO4(aq) → K2SO4(aq) + CuF2(aq) + 2H2O(l)
Now you have the balanced chemical equation for the addition of aqueous potassium fluoride to aqueous copper(II) sulfate.
