19.4 How to Calculate Standard Cell Potential | General Chemistry

Chad demonstrates how to calculate Standard Cell Potential (a.k.a. emf or voltage) from a Table of Reduction Potentials. He uses both of the commonly used equations and shows the difference between the two and where NOT to make a mistake.
Ecell = Ecathode - Eanode
Ecell = Ereduction + Eoxidation
The Standard Hydrogen Electrode (SHE) is also identified and its importance as a reference electrode is described. Finally, it is demonstrated how to use a Table of Reduction Potentials to identify the strongest oxidizing agent, the strongest reducing agent, and when two species will react spontaneously in a redox reaction.

    Wow! This video was put together beautifully and I really appreciate you helping by making this topic simple for me to understand. This video has gotten me through the hardest times, every hurdle had in my life, I wouldn't be able to get through electrochemistry if it weren't for you Mr. Chad

    How does any of this work with organic batteries? Like the battery using the oxidation of hydroxyquinones to quinones? (I think it's otherwise known as the rutabager battery?) I do not see a charge change for =O vs -OH groups. Does it matter if it's in aqueous vs non aqueous solution? Is there a table of redox potentials of covalently bound functional groups in organic molecules? Would an aromatic sulphur ylide in dsmo work similar to a quinone in aqueous solution electrochemically?

    It's the strongest reducing agent thus it gains electrons at the cathode (cations)

    I'm curious if you're a Christian because I noticed you wearing a shirt with a Bible verse on it in one of your videos. If you say yes, I'm even happier since you're a fellow brother in Christ, if not that is also fine. You are not only a genius, but also a man of God, who uses his God-given abilities to help us all. May the Lord bless you with many years of good health and success.
