9. Double Replacement Reaction Notes
Predicting Products and States

10. What is a double replacement reaction?
Two ionic compounds react to form two new ionic compounds; “switching partners”
General Equation: AB + CD  CB + AD
Examples:
3 CaCl2 + 2 AlN  2 AlCl3 + Ca3N2

11. Double Replacement Reactions
Cations switch places with cations OR think of it as “metals switching with metals”
3 CaCl2 + 2 AlN  2 AlCl3 + Ca3N2

12. In double replacement reactions:
If a gas, water, or precipitate is not formed, the reaction will not take place
Determine and write states of products for double replacement reactions
Gas(g)
Precipitate (s)
Aqueous solution (aq)
Liquid (l)

13. Use solubility rules to determine the state of:
MgSO4
(aqueous)
AgCl
(solid)

14. Predict the Products! Barium Chloride + Sodium Sulfate 
BaCl2(Aq) + Na2SO4(Aq) 
BaCl2(Aq) + Na2SO4(Aq) BaSO4(s) + 2NaCl(Aq)

15. Predict the Products Cobalt Chloride + Sodium Sulfate 
CoCl2(aq) + Na2SO4(aq) →
CoCl2(aq) + Na2SO4(aq) → CoSO4(aq) + 2 NaCl(aq)
CoCl2(aq) + Na2SO4(aq) →No Reaction
