Finish the equation:
Solutions of zinc sulfate and sodium phosphate are mixed
produces zinc phosphate plus sodium sulfate.
Look up the solubility of zinc phosphate. I think it is insoluble in water.
together to form a precipitate. The balanced equation for this reaction can be written as:
ZnSO4 + Na3PO4 → Zn3(PO4)2 + Na2SO4
In this equation, zinc sulfate (ZnSO4) reacts with sodium phosphate (Na3PO4) to form zinc phosphate (Zn3(PO4)2) and sodium sulfate (Na2SO4).
To finish the equation, you need to write down the balanced chemical equation for the reaction between zinc sulfate and sodium phosphate. Here's how you can do it:
1. Determine the chemical formulas of zinc sulfate and sodium phosphate:
- Zinc sulfate: The formula for zinc sulfate is ZnSO4.
- Sodium phosphate: There are several types of sodium phosphate, but for this equation, we'll use the formula Na3PO4.
2. Write down the balanced chemical equation by combining the two compounds:
ZnSO4 + Na3PO4 →
At this point, you need to determine the products of the reaction. To do that, you need to consider the charges of the ions:
- The sulfate ion (SO4) has a charge of -2.
- The zinc ion (Zn) has a charge of +2.
- The sodium ion (Na) has a charge of +1.
- The phosphate ion (PO4) has a charge of -3.
Since the charges need to balance in a neutral compound, you can swap the numbers of the charges in order to balance them.
3. Balance the charges by swapping the numbers:
ZnSO4 + 3Na3PO4 →
Now, we need to determine the individual ionic compounds that form as products.
- The zinc ion (Zn) combines with the phosphate ion (PO4) to form zinc phosphate, Zn3(PO4)2.
- The sodium ion (Na) combines with the sulfate ion (SO4) to form sodium sulfate, Na2SO4.
4. Write down the final balanced chemical equation:
ZnSO4 + 3Na3PO4 → Zn3(PO4)2 + 3Na2SO4
So, the final equation is: Solutions of zinc sulfate and sodium phosphate are mixed to form zinc phosphate (Zn3(PO4)2) and sodium sulfate (Na2SO4).
Zn2+ + PO43->Zn3(PO4)2
