These ions are same in both side of chemical reaction. A net ionic equation shows only the chemical species that are involved in a reaction while a complete ionic equation also includes the spectator ions. The net ionic equation is commonly used in acid-base neutralization reactions double displacement reactions and redox reactions.
Notice that in writing the net ionic equation the positively-charged silver cation was written first on the reactant side followed by the negatively-charged chloride anion.
A solution is prepared by mixing 1500 mL of 10 10-2 M PbNO32 and 750 mL of 15 10-3 M NaF. PbF2s dissociation can be represented as PbF2s lt. OOOO HOCH-HOCI H HOCI - HOCI HCI HOCI-H2O Cl2 H H2O - HO HOCIH OCI. It is often written for reactions that occur in aqueous solution.
