- Michael Faraday (1791-1867) is most famous for his contributions to the understanding of electricity and electrochemistry.
- Hi I'm Michael Faraday
- Electrochemistry is everywhere
- Electrochemistry is defined as the branch of chemistry that examine the phenomena resulting from combined chemical and electrical effects.
- There are 2 types of process. The electrolytic process, reactions in which chemical changes occur on the passage of an electrical current. The galvanic or voltaic process, chemical reactions that result in the production of electrical energy.
- What are the types of process this field covers?
- What is electrochemistry?
- Reactions-half cell and overallAt each electrode, an electrochemical reaction occurs. This reaction is called a half cell reaction. The overall chemical reaction of the cell is given by combining the two individual half cell reactions.Half cell reaction types:-Oxidation reactions-Reduction reactions A reaction is classified as oxidation or reduction depending on the direction of electron transfer.
- An electrochemical cell typically consist of:
- -Two electronic conductors (also called electrodes)- An ionic conductors (called an electrolyte)
- electronics
