Electrolysis of Water & Hydrochloric Acid
The discovery that passing an electric current through water would split it apart was made quite soon after the discovery of current electricity itself. This predates Michael Faraday’s work in this area, but it is he who introduced most of the terms that we still use today. Electrolysis was named by Faraday. Though not an exact translation, it means to use electricity to split something apart.

Why such channel is so underrated while those which is uneducational get higher views. Keep up the great work, I really like it.

Yeah.....true👍

One thing that you missed was to tell the viewers why do we do electrolysis? I think that is the first question that comes to mind when we hear about electrolysis...... Btw great job to make people familiar with such things I'm blessed coz I m chemist

[@totu7071]

Accurately explained and easy to understand. If anyone is going through the comments to check, I assure you that you will understand it very well. I advise you to watch it a few times for it to stick in your mind. I thank everyone who took the trouble to make this video. It is very helpful.

[@fuseschool]

Thank you so much! That's really nice of you 🙂

[@damedesmontagnes]

The hydrogen and oxygen gas that is formed are neutral charged? So they won't attach to virus protein spikes and form OH- to draw out the H+ from the virus and destroy it? Need H+ and O2-

[@fuseschool]

Hydrogen and oxygen are neutral gases. Ions only exist at room temperature in solids and liquids. Destroying viruses is quite another matter.

[@coffeecuppepsi]

I'm trying to learn chemistry maybe someone can help me. i dissolved table salt in hot tap water until it was saturated. then ran 6 amps thru it using tinfoil electrodes. it fizzed a lot :) the tinfoil on the positive terminal completely disintegrated. I was left with a clear gel like substance floating on the surface... texture like glycerin.. what could this have been? EDIT: I couldn't smell Chlorine gas given off so i assume it became part of the gunky stuff?

[@abhishekguptaiitguwahati3092]

If you have 1 M HCl then at cathode reduction of H20 take place ?

[@sarahkhan2411]

Hy. Love your ways of explaining. This channel has helped me alot and especially during this pandemic. I have a small request, plz may you also post o video where it shows how electrolysis is used for hair removal and which anodes and cathodes are used for this process. Love 💓 Sarah

Thanks, Sarah! Glad our channel helped you 🙂 that's an interesting suggestion, we'll ask our teachers 😉

but why is water always said to be away from electric stuff? If it's not a conductor

[@fuseschool]

"It’s not actually the water itself which disagrees with electricity, it is the impurities in the water such as minerals and dust which conduct electricity to cause a reaction." www.winnsservices.co.uk/news/why-water-and-electricity-are-a-deadly-combination

OH ion decomposes into O2 + H2O + e- In this how water comes in equation?? Confused a lot

[@keithross7058]

Think of the overall equation for the electrolysis: two water molecules split into an oxygen and two hydrogen molecules as gases HOH + HOH = HH +HH+OO When this reaction happens at the two separate electrodes we could have had H+ H+ and O- - as the ions, but water doesn't ionise completely like that. Only one H+ ion is produced making the oxygen still bonded to one other hydrogen giving us OH- ion. When these lose their electron at the anode they reform water and the oxygen is given off OH- + OH- --> O + HOH + e- + e- (and two O atoms join to form a molecule of oxygen)
