QUESTION

# Write a balanced equation for copper 2 sulfate with sodium carbonate to produce copper 2 carbonate and sodium sulfate. Can you please help me?

Here's what I got.

First, your general chemical reaction looks like this:

CuSO_(4(aq)) + Na_2CO_(3(aq)) -> CuCO_(3(s)) darr + Na_2SO_(4(aq))

Copper(II) sulfate, CuSO_4, and sodium carbonate, Na_2CO_3, are soluble in aqueous solution, which means that they will dissociate into cations and anions.

The reaction produces copper(II) carbonate, CuCO_3, an insoluble solid that precipitates out of solution, and aqueous sodium sulfate, Na_2SO_4.

The complete ionic equation is:

Cu_((aq))^(2+) + SO_(4(aq))^(2-) + 2Na_((aq))^(+) + CO_(3(aq))^(2-) -> CuCO_(3(s)) darr + 2Na_((aq))^(+) + SO_(4(aq))^(2-)

The net ionic equation, which you get after eliminating spectator ions, is:

Cu_((aq))^(2+) + color(red)(cancel(color(black)(SO_(4(aq))^(2-)))) + color(red)(cancel(color(black)(2Na_((aq))^(+)))) + CO_(3(aq))^(2-) -> CuCO_(3(s)) darr + color(red)(cancel(color(black)(2Na_((aq))^(+)))) + color(red)(cancel(color(black)(SO_(4(aq))^(2-))))

Cu_((aq))^(2+) + CO_(3(aq))^(2-) -> CuCO_(3(s)) darr
