Question

What is the complete ionic equation and the net ionic equations for the reaction of Ca(No3)2 and Na2SO4? which are the spectator ions?

Explanation / Answer

A complete, or total, ionic equation shows all the ions that are floating around in the reaction mixture... The Net ionic equation only shows the ions that are participating in the reaction. You leave out the spectator ions.. eg Molecular equation 2AgNO3(aq) + FeCl2(aq) -------------> 2AgCl(s) + Fe(NO3)2(aq) Any compound in aqueous (aq) solution exists in the solution as dissociated ions eg AgNO3 ---------------> Ag+(aq) + NO3-(aq) FeCl2 -----------------> Fe2+(aq) + 2Cl-(aq) So write out all the ions in the mixture to give your Complete ionic equation 2Ag+(aq) + 2NO3-(aq) + Fe2+(aq) + 2Cl-(aq) ------> AgCl(s) + Fe2+(aq) + 2NO3-(aq) Now you can see that there are 2NO3-(aq) and Fe2+(aq) on BOTH sides of the equation. SO they did not change during the reaction. They did not participate so they are spectator ions. They are left out of the Net ionic equation 2Ag+(aq) + 2Cl-(aq) -------------> 2AgCl(s) eg2 molecular 2NaOH(aq) + H2SO4(aq) -----> Na2SO4(aq) + H2O(l) Complete Ionic 2Na+(aq) + 2OH-(aq) + 2H+(aq) + SO4(2-)(aq) ---> 2Na+(aq) + SO4(2-)(aq) + H2O(l) Net ionic 2H+(aq) + 2OH-(aq) -----> 2H2O(l) eg3 molecular Ba(OH)2(aq) + H2SO4(aq) ------> BaSO4(s) + H2O(l) Complete ionic 2Ba2+(aq) + 2OH-(aq) + 2H+(aq) + SO4(2-)(aq) ------> BaSO4(s) + H2O(l) note that there are no spectator ions in this case, so Net ionic equation = Complete ionic equation 2Ba2+(aq) + 2OH-(aq) + 2H+(aq) + SO4(2-)(aq) ------> BaSO4(s) + H2O(l)
