Question

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

Answer 1

Double displacement reaction is one in which both the reactants are ionic and the cations and anions of both these compounds switch their places. In a double displacement reaction, one of the product is either an insoluble precipitate or a gas or water as seen in case of neutralization reaction.

The given double displacement reaction is between Sodium phosphate
`Na_(3)PO_(4)`and copper sulfate
`CuSO_(4)`. When the ions of both compounds switch their places, we get Sodium sulfate
`Na_(2)SO_(4)` and copper phosphate
`Cu_(3)(PO_(4))_(2)` as the products.

The balanced chemical equation for this reaction can be represented as:

2
`Na_(3)PO_(4)`(aq)+3
`CuSO_(4)`(aq)-->3
`Na_(2)SO_(4)`(aq)+
`Cu_(3)(PO_(4))_(2)`(s)
