Write the equation for the reaction of ion exchange of sodium carbonate with sulfuric acid in molecular, full and short ionic form.

To begin with, we will write down the reaction equation for all three stages (molecular, ionic and short ionic):
The complete molecular equation of this reaction is written with the full names of the reagents and products):
Na2CO3 + H2SO4 = Na2SO4 + CO2 + H2O
The complete ionic equation of this reaction (ionic dissociation of reagents and reaction products):
2Na (+) + CO3 (2-) + 2H (+) + SO4 (2-) = 2Na (+) + SO4 (2-) + CO2 + H2O
Short ionic equation (ions that do not cancel out): CO3 (2-) + 2H (+) = CO2 + H2O
