Exploring Electrochemistry: Power from Chemical Reactions

Learning objective

Learning Objective

At the end of the lesson, you will understand basic electrochemical concepts and how redox reactions generate electricity.

What do you already know about how batteries work?

What is Electrochemistry?

Electrochemistry studies chemical processes that cause electrons to move, generating electricity. It involves redox reactions.

Redox Reactions

Redox reactions involve the transfer of electrons between two substances. Oxidation is loss, and reduction is gain of electrons.

Galvanic Cells

Galvanic cells convert chemical energy to electrical energy. They have two electrodes in electrolytes connected by a salt bridge.

How Batteries Work

Batteries are practical applications of galvanic cells. They store and provide electrical energy through redox reactions.

Standard Electrode Potentials

Standard electrode potential measures a substance's tendency to lose or gain electrons. It predicts redox reaction direction.

Applications of Electrochemistry

Electrochemistry is used in electroplating, corrosion prevention, and manufacturing processes like electrolysis.
