What is the complete ionic equation for H2SO4 (aq) + Cal2 (aq) - > CaSO4 (s) + 2HI (aq) ?

2H (+) + SO4 (2-) + Ca (2+) + 2I (-) - > CaSO4 (s) + 2H (+) + 2I (-)

The signs in brackets are the subscripts for the charge of the ion. This is the complete ionic equation. The net ionic equation is:

Ca (2+) + SO4 (2-) - > CaSO4
