AP Chemistry / Unit 4: Chemical Reactions
4.2 Net Ionic Equations
Notes
Write strong electrolytes as ions, cancel spectator ions, keep what changes.
- Example: $AgNO_3+NaCl$ gives $Ag^+(aq)+Cl^-(aq)\to AgCl(s)$.
Practice
Spectator ions in the reaction of $\mathrm{AgNO_3}$ and $\mathrm{NaCl}$:
They don't change.
Net ionic equation for $HCl+NaOH$:
Strong acid and base.
Which is written as ions in a net ionic equation?
Only dissolved strong electrolytes split.
