Study Notes
Electrochemical Reactions
- An electrochemical reaction is distinguished from a conventional chemical reaction by the involvement of an electric current or potential difference.
- In electrochemistry, the relationship concerned with is the connection between chemical reactions and electricity.
William Gilbert and Magnetism
- William Gilbert is known as the 'Father of Magnetism' for his work on magnets.
- Gilbert spent 17 years experimenting with magnetism.
Electrochemical Reactions vs. Conventional Chemical Reactions
- The distinguishing factor between electrochemical reactions and conventional chemical reactions is the presence of an electric current or potential difference in electrochemical reactions.
History of Electrical Matters
- The understanding of electrical matters began in the 17th century.
Electrolytes
- An electrolyte plays a crucial role in electrochemical reactions, enabling the flow of electric current.
Electric Batteries and Fuel Cells
- An electric battery or fuel cell is distinguished from electrolysis in terms of electrical potential difference, with the former producing a potential difference and the latter requiring one to operate.
