Question

PLEASE HELP, I NEED TO GET THIS DONE TODAY

Create a balanced reaction for the double displacement reaction between Sodium Phosphate Na3(PO4) and Copper Sulfate Cu(SO4)


You will have to balance the ion ratios of the products as well as the over-all reaction for full points.

Here are some ion charges that may help you balance the products:

Ion charges: (Zn2+, Cu2+, SO42-, Al3+, Ag1+, NO31-, Cl1-, OH1-, PO43-, Na1+)

• Ionic compounds correct

• Ionic compounds balanced internally

• Reaction balanced

• Correct formatting (superscript and subscript, for example)

Answer 1

The balanced reaction is

3Na3PO4 + 2CuSO4 ------> 3Na2SO4 + Cu3(PO4)2

To balance this reaction of double displacement, we see first that this reaction maintain the valence numbers of every atom.

Then, to have the same value of Na in the two sides of the reaction we multiply for the number of the other side. So,

(Na3PO4)x 2

(Na2SO4)x3

As we can see either, we need to balance PO4 cause there are two molecules of this in the reactant side, so we have two molecules of PO4 in the product either.

Then we get

3Na3PO4 + 2CuSO4 ------> 3Na2SO4 + Cu3(PO4)2

To probe that balance was correct, you can verify that the charges are exactly the opposite.
