A net ionic equation can then be written which shows the actual reaction that occurs at the ionic level. In this net ionic equation, spectator ions (ions that appear on both sides of the equation in the same form) are cancelled out to yield the net ionic equation.
A) 2HCl(aq) + Ca(OH)2(aq) -> 2H2O(l) + CaCl2(aq)
B) 2NaOH(aq) + H2SO4(aq) -> 2H2O(l) + Na2SO4(aq)
C) NaCl(aq) + AgNO3(aq) -> AgCl(s) + NaNO3(aq)
D) H2(g) + Cl2(g) -> 2HCl(g)
