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.

  1. weeks of work taught in 5 minutes…… Thank you for this!

  2. i am very thankful to you
    this video saved my too much time because i was unable to understand this topic but by this video i understood at first time only


  4. Thanks fuseschool with your help, all my exam papers will be a walk in a park

  5. I've been trying for a year to understand electrolysis to no success. But after watching this video for just 3 minutes i completely understood it.

  6. Electrolysis means splitting By electricity. Electricity is applied to separate it from its compound. During the process of electrolysis the positive and negative ions attract each other . The positive one move to the negative side and the negative one moves to the positive one. Electrolysis only depends on these things the ions need to move frequently. It needs to dissolved in water or to be melted for free ions to move.

  7. My teacher could not explain this simply but you my friend are the best

  8. I just started this topic and it was quite helpful watching this as it helped me understand

  9. Electrolysis means splitting by electricity. An electricity is applied to separate an ionic compound when it is molten or dissolved. There is a battery operated between the positive and negative electrode. Positive will attract the negative and negative will attract the positive during the process of electrolysis. At the down portion there will be electrolyte. For the main attempt of electrolysis, it should made of ions and it have to be molten or dissolved so, the ions are free to move. The positive calles anode and the negative one called cathode.

  10. Why do the charges of the electrodes oppose the direction of current. Negative electrons leave a positive electrode and go towards a negative electrode; I don't understand. And if it's conventional current that means voltaic cells have it wrong. Whats up?

  11. I think schools should close and government should tell students to read from YouTube

  12. thanks a lottttttttttttttttttttttt……………………………!!!!!!!!!!!!!!!!!!

  13. Why would 598 people dislike this video? 🤔

  14. Thank you but I am good teacher than you so my children in schools don't prefer you so you are a not a high level tr so don't be proud of you

  15. Please be my chemistry teacher ….IT WAS SO HELPFUL THANKS A LOTT

  16. that was short crisp and very easy to understand….also the subtitles were huge! help ..thank you

  17. You just saved my ass. I was trying to find this perfect explanation for a week and now 2 days before my combined science exam I found the best video. Thank you so much

  18. You made a big mistake in the whole electrolysis process as copper electrode in active electrode

  19. I watch these because we don't have school due to Covid and there's no practicals doing…. Thank you soooo much… 😉

  20. I don't understand how is the solution conducting electricity are the electrons leaving the electrodes and go into the solution and travel to the other electrode or What?

  21. Thanks. I wasnt able to understand this process also after trying a lot … but after i watched this video i understood clearly.

  22. This is so simple and easy to understanddd

  23. Very bad definition. I did not understant a single thing

  24. GOOD LUCK everyone in your exams ❤️love you 🤍

  25. Thank you so much FuseSchool, i study in 8th class and this helped a lot coz it was easy to understand. 🙂

  26. Thank you So much! You Saved My Chemistry Exam

  27. So we as in Humans are electric Dowsing rod ,which turns the iron to cancer ?!

  28. THANKS FOR TEACHING US. LOVE FROM INDIA 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳
