1. Redox Reactions

2. Electrochemistry
The study of chemical reactions involving the transfer of electrons between reactants.

3. Super Useful! You can find electrochemistry in
Combustion and explosions
Photosynthesis and Cellular respiration
Mining of ores
Rust and Corrosion
Batteries
Jewelry making and photography
Creation of chlorine for pools and hydrogen for fuel cells

4. Oxidation The loss of electrons is oxidation Occurs at the ANODE
Reducing agents undergo oxidation (donate electrons and cause reduction)

5. Reduction The gaining of electrons Occurs at the CATHODE
Oxidizing agents undergo reduction (gain electrons by causing oxidation)

6. Redox Reactions Write down all reactions
Dissociate all molecules into ions
Label oxidizing agents and reducing agents
Find the strongest oxidizing agent and reducing agent (according to the chart)
Write the half reactions (SOA left to right, SRA right to left)
Balance the electrons and combine the reactions

7. Example 1
Copper metal is placed in a solution of acidified silver chloride. Write a balanced redox equation for the reaction of copper metal with silver chloride.

8. Example 2
Demonstrate the balanced net ionic equation for the reaction of copper metal with sulfuric acid under idea conditions (used in refining copper ores)
