The balanced equation is 3 Na₂CrO₄ + 3 AlPO₄ ⇒ 2 Na₃PO₄ + Al₂(CrO₄)₃.
Let's consider the unbalanced chemical equation that occurs between Na₂CrO₄ and AlPO₄. This is a double displacement reaction.
Na₂CrO₄ + AlPO₄ ⇒ Na₃PO₄ + Al₂(CrO₄)₃
We will balance it using the trial and error method.
First, we will balance Na atoms by multiplying Na₂CrO₄ by 3 and Na₃PO₄ by 2.
3 Na₂CrO₄ + AlPO₄ ⇒ 2 Na₃PO₄ + Al₂(CrO₄)₃
Finally, we get the balanced equation by multiplying AlPO₄ by 3.
3 Na₂CrO₄ + 3 AlPO₄ ⇒ 2 Na₃PO₄ + Al₂(CrO₄)₃
The balanced equation is 3 Na₂CrO₄ + 3 AlPO₄ ⇒ 2 Na₃PO₄ + Al₂(CrO₄)₃.
