Introduction to Electrochemistry

Published on August 26, 2015 by

Everything you need to know about Electrochemistry. Electrochemistry is the relationship between electricity and chemical reactions. There are two ways that electricity and chemical reactions interact: certain chemical reactions can create electricity, and electricity can force certain chemical reactions to happen that wouldn't happen otherwise. We'll look at two very common examples in electrochemistry. We'll see how a galvanic or voltaic cell uses a chemical reaction to create electricity, and we'll see how electrolysis uses electricity to cause water to decompose into hydrogen and oxygen gas. We'll also look at the list of Standard Reduction Potentials, to figure out what chemical reactions will happen on their own (are spontaneous) are can create electricity, and which will not happen on their own (are not spontaneous) and require electricity to happen.

    Like most of Tyler’s videos this is very clearly and methodically laid out at a good level that communicates with introductory level students. I do think there is an important bit missing in the description of the galvanic cell as it won’t work at all if there is no completion of the circuit to replenish negative charge in the anode compartment. Conventionally this is the salt bridge.

    How come the Standard Reduction Potentials chart changes? In the first example you/he did it was different from the second one later in the video.

  • HeyHannah 2 years ago

    Wow omg Iโ€™m only 2 min into the video and I had to pause to tell you how grateful I am for this video. My entire life Iโ€™ve always been perplexed by the concepts of electricity and ion movement in real settings and now I feel like I FINALLY understand some of it on a fundamental level. Youโ€™ve helped teach me something in 2 min that 20 years of the education system hasnโ€™t. From the bottom of my heart, thank you.

    Also, please make more videos!!! Iโ€™d love to see some o chem or biology videos ๐Ÿ™‚
