Electrolysis

Definition

The breakdown of an ionic compound, molten or in aqueous solution, by the passage of electricity.

Positive ions move to the cathode and gain electrons; negative ions move to the anode and lose them.

cathode − anode +
Exam tipAlways write “molten or aqueous” — leaving it out is one of the most common lost marks on this definition.

What students say

Unprompted, from students who’ve actually used it

I read the sources of finance chapter the same day as my test — question 4(b) was on exactly that topic. I've never flowed like that on it before.

Questions

Before you start

Something else? Get in touch.

Is it really free to read?

Yes — every published topic is free to read in full. No account, no card details, no trial that expires.

Does Glide have past papers?

Yes. Past papers with mark schemes are available for Chemistry, Physics, Business Studies, Mathematics, Biology, Economics, Accounting, Computer Science, First Language English, History and Geography, from 2021 to 2025. Filter by year, session and paper and open the PDF in one click. For Chemistry, Physics and Mathematics the papers listed are the Extended written papers. They are free, and the PDFs are hosted by Xtreme Papers rather than on glidenotes.org.

Do I need an account?

No. There are no accounts anywhere on Glide. Open a topic and start reading.

Which subjects are actually finished?

Being upfront: not all of them. 7 subjects are complete — every topic written and published. The rest are on the roadmap, and every subject page shows exactly where it stands.

How do you know the notes are accurate?

Every topic is derived from an approved Glide chapter and checked against the Cambridge syllabus. Where a point is Extended-only, it is marked as Extended rather than blended into the core content.

Will more subjects and topics be added?

Yes — new topics are published as they are written and checked. The subjects page always shows what is live right now.
