Term
Writing Net Ionic Equations
Definition
1. Write reactants.
2. Write products by exchanging cations.
3. Dissociate (write as ions) ALL soluble salts, strong acids, and strong bases (except Ca(OH)2)
Reminder: Do not break up polyatomic ions i.e.) K_2_SO_4_ --> 2 K^+ + SO4^2- NOT S2- + 4 O2-
4. Balance.
5. Cross out identical (spectator) ions on both sides of the equation.
6. Rewrite NET IONIC EQUATION. CHECK atom and charge balance.
Term
