Electrolysis, Taught not just answered.
A real-time, 1:1 lesson on Electrolysis: an AI teacher explains it out loud while it visualizes every step. Interrupt it, ask why, and it checks you got it, in 26 languages.
The idea
What is Electrolysis?
Electrolysis is the use of electric current to drive a chemical reaction that would not happen on its own. A molten ionic compound or a solution is placed between two electrodes connected to a power supply. Positive ions move to the negative cathode and are reduced by gaining electrons; negative ions move to the positive anode and are oxidised. In aqueous solutions water can compete, so which ion is discharged depends on position in the reactivity series and concentration.
Where it appears: Class 10 and 12 CBSE and ICSE, GCSE and A-level, IB Chemistry, JEE and NEET.
Where learners get stuck
Why Electrolysis is hard
Learners expect the same ions to discharge in solution as in the melt, and forget that water can be oxidised or reduced instead; they also confuse the electrode signs with those in a galvanic cell.
The picture a good explanation starts with: A beaker of electrolyte with two electrodes wired to a battery, positive ions migrating to the cathode and negative ions to the anode, with electron flow marked in the wire.
A lesson, step by step
How a lesson on Electrolysis goes
01
Ask
Type or say "Why does electrolysis of brine give hydrogen instead of sodium?" in your own words, in any of 26 languages.
02
Plan
The tutor plans a storyboard, one picture per idea, starting with a beaker of electrolyte with two electrodes wired to a battery, positive ions migrating to the cathode and negative ions to the anode, with electron flow marked in the wire.
03
Explain
It explains Electrolysis out loud while the picture builds step by step, pitched to your level (Class 10 and 12 CBSE and ICSE and up).
04
Interrupt
Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.
05
Check
A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.
06
Your notes
Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.
Ask it anything
Questions learners ask about Electrolysis
- Why does electrolysis of brine give hydrogen instead of sodium?
- How do I predict the products at each electrode?
- How is the mass deposited related to the current and time?
Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.
Questions
Asked, Answered
Can LetMeTeach explain Electrolysis?
Yes. Ask in your own words and the tutor plans a lesson on Electrolysis: it starts with a beaker of electrolyte with two electrodes wired to a battery, positive ions migrating to the cathode and negative ions to the anode, with electron flow marked in the wire. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.
Where does Electrolysis come up?
Class 10 and 12 CBSE and ICSE, GCSE and A-level, IB Chemistry, JEE and NEET. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.
Can I learn Electrolysis in my own language?
Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
