1. Single Displacement and Redox

2. Single Displacement and Redox: At the conclusion of our time together, you should be able to:
Identify a basic single displacement reaction
Use the reactivity series table to determine if the reaction will take place
Show the change in oxidation numbers for a single displacement reaction

3. 3. Single Replacement Reactions
Single Replacement Reactions occur when one element replaces another in a compound.
A metal can replace a metal (+) OR a nonmetal can replace a halogen (-).
element + compound element + compound
A + BC  AC + B (if A is a metal) OR
A + BC  BA + C (if A is a halogen)
(remember the cation always goes first!)

4. 3. Single Replacement Reactions
For these reactions, you must remember:
When H2O splits into ions, it splits into H+ and OH- (not H+ and O-2 !!)
A single replacement reaction will only occur if the replacement ion has a higher activity than the original ion in the compound
To determine this, refer to a relative activity table

5. Single Replacement Reactions
(note: Li is higher relative activity than H):

6. A displacement reaction: metallic copper with silver nitrate
                                                                                           
Cu + Ag NO3
Note: Cu is higher relative activity
Ag + Cu(NO3)2
