What Is Electrolysis | Reactions | Chemistry | FuseSchool

Electrolysis is electrical current flow through a liquid which causes chemical changes. The liquid can be a molten ionic compound or aqueous solution. The liquid will contain free-flowing positive ions and negative ions. The positive ions are called cations, and the negative ions are called anions.

Electrodes are submerged in the liquid (electrolyte solution) and connected to an electrical cell. The electrons will start to flow in the wires and this will cause one electrode to become positively charged (the anode) and the other negatively charged (the cathode). This has an immediate knock-on effect in the molten liquid, and the ions in it. The positive ions in the liquid (electrolyte) are attracted to the negative electrode (cathode). The negative ions in the liquid (electrolyte), is going to be attracted to the positive electrode (anode). This is because opposite electrical charges attract. When the ions meet the electrodes, electron exchange happens and this triggers a chemical reaction. Remember that electrolysis can also take place in ionic solutions as well as molten compounds. The more concentrated the solution, the greater the ion flow rate. Ion flow rate can also be increased by increasing the potential difference or voltage across the cell.

You've just saved my chemistry GCSE. I haven't been able to understand this all year and I finally understand it the day before my exam 😅

[mujalak]

OMG, thanks sooo much... you are better than my chemistry teacher, She couldn't teach me electrolysis in two years while you sir taught it to me in just 5 minutes!

[elisedove]

I am a teacher, and you are a very good teacher teacher.

[dogissky]

3 years of not understanding electrolysis at school and it's stuck in my head from a 5 minute video!!! Thanks! :)

Imagine having A chemistry Teacher like him at school...

[amzalahmed]

a quick lesson that retains in my memory. well done

[ebony]

Thank you so much. This was so helpful. My chemistry teacher kind of rushed over the beginning of electrochemistry and electrolysis so when he moved on I was still confused about the structure of the beaker and power supply and why the ions flowed the way they did. This video connected all the dots for me.

I've my chemistry exam tommorow and the way you explained it was incredible, I'm definitely passing my exam tomorrow!! thank youuu

[cuberynth]

This saved me .I wasn't able to understand the concept for a while but this was simple to follow and not too long which meant it won't start to get boring.thankyou so much

I would just like to say: thank you SO much for this video! Before this, I kind of got the idea of electrolysis, but it seemed so complicated to me. The textbook confused me, but with this video, it just clicked inside my head!! You explain it so clearly. Once again, a massive thank you!

[oliviaelliott]

I’ve been studying this for a term and never got it.. this 5 minutes video just made me understand so much more. Thanks!

[itzmaliaa]

thanks a lot for all of these videos, I have my igcse's in four months and this helps a lot!!!

[giuliogrech]

This actually really helped me. Im bad in chemistry and never understood electrolysis till now. The example was amazing btw easier for most people to understand through examples

[theguys]

Fuse school is absolutely the best...I could understand things in few minutes which I've been struggling to learn for past few years..this is sooo helpful ..thanks❤️

Hello! I am a Chemistry teacher and I was looking for interesting videos to show to my lecture group next week. I know FuseSchool channel is one of the best out there!

For this particular video, I noticed a tiny error at around 2:14 min. The battery is placed the wrong way around with respect to the movement of electrons. (Same animation mistake at 5th minute)

The battery is correct at 3:30min though. :-)

Thanks again for a great video!

[sarahscheyerle]

Nice video :D - I saved it to my 'Chemistry' playlist

[sojanjose]

It is a great thing that you have taught in detail about electrolysis

[marcuscostello]

thanks for helping me with knowing what electrolysis is and you helped me with my science fair

[engineering]

This was a phenomenal explanation! I wish these videos existed when I was in high school

[numadevi]

such a gud video... I really understood electrolysis in juz 5 mins....thank u much!
