9. Writing Net Ionic Equations

10. Net Ionic Equations
In a double replacement reaction, not all ions are involved in the reaction
“spectator ions”
We write net ionic equations to determine what actually reacted

11. Net Ionic Equations Example
Molecular:
BaCl2(aq) + Na2SO4(aq)  2 NaCl(aq) + BaSO4(s)
Complete Ionic:
Ba+2(aq) + 2 Cl-1(aq) + 2 Na+1(aq) + SO4-2(aq)  2 Na+1(aq) + 2 Cl-1(aq) + BaSO4(s)
Net Ionic:
Ba+2(aq) + SO4-2(aq)  BaSO4(s)

12. Net Ionic Equations Practice
Complete the practice at your desk. Whatever you do not finish will become your HW.
