Net-Ionic Equations
- A representation of a chemical reaction→ must be balanced!
- On AP exam, if coefficients are given can assume that the equation is balanced
- Balanced Formula/molecular equation: show all species participating in reaction
- These equations indicate that mass is conserved
- Ex:
- Complete ionic equation: strong electrolytes (aq) are ions
- Remember:
- All ionic compounds (salts) and strong acids/bases are strong electrolytes
- Solubility rules and if product forms as a solid or not
- Ex:
- Keep liquids (H2O (l)), solids, and gases together
- Net ionic equation: Spectator ions are not included
- Used to represent only the substance undergoing a chemical change
→ 
- Spectator ions: ions that do not participate directly in the reaction; are on both sides
- Ions that participate react to form a solid
- A dissolution equation will show show a solid substance forming aqueous ions
- Ex:
- Ex:
