Success 24/7 Chemistry Notes: Net Ionic Equations
Net Ionic Equations - Indicates only those particles that actually take part in the reaction
Steps to writing the net ionic equation:
1. Write a balanced chemical equation.
2. Write a complete ionic equation that shows compounds as their free ions.
Do not change (s), (l), or (g).
3. Cancel out ions that appear on both sides. These are called “spectator ions” and are not
involved in the reaction.
4. Write the net ionic equation with the remaining substances.
KCl(aq) + AgNO3 (aq) → KNO3(aq) + AgCl(s)
BaCl2 (aq) + Na2SO4(aq) → BaSO4(s) + NaCl(aq)
Mg(s) + HCl(aq) → MgCl2(aq) + H2(g)
Al(NO3)3 (aq) + Ba(OH)2 (aq) →
Lead (II) nitrate and sodium chloride →
