    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.
