Electrochemistry's Biggest Secret: The Voltage In Every Metal - Standard Hydrogen Electrode

In this video, we explore the concept of electrode potentials, explaining how they work and their importance in chemistry. We'll cover what a standard electrode potential is, how half cells and electrochemical cells are connected to these potentials, and how they help us compare the reactivity of different elements. You'll also learn how potential differences between half cells indicate whether oxidation or reduction is more likely to occur.
We also discuss the standard hydrogen electrode, the use of standard conditions, and their connection to the electrochemical series.
