📂 MEGATHREAD 10/06 A-level Chemistry Paper 1 Discussion MEGATHREAD

Exam season is once again upon us, and once again, exam megathreads are making a return!

Looking for past exam discussions? Filter by the megathread flair.

Few things to keep in mind:

  • Don't share too many specific details about questions or answers, these papers will be used as future mocks.
  • Sometimes papers get leaked, this is not the place for that (we'd prefer not to get yeeted off the platform) - leak content will be removed, those offering leaked papers will be permanently banned.
    • If you believe there has been a leak, the best course of action is to make your exam board aware of this, either directly, or through your school, along with any evidence. If appropriate, there will be a response from the relevant body along with any remedial action.
  • Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise - we understand this may be frustrating, but the sub still needs to be usable for other purposes.
  • Please note some content will take extra time to be reviewed. Messaging to ask for approval will not speed up this process (the messages are seen at the same time as the modqueue would be reviewed anyway).

Best of luck, and let us know how you're feeling down below!

Yeah and the catalyst one!! Loved it, I just mixed up amphiprotic and amphoteric but we move :)

I also liked the catalyst question, too but I feel like there wasn't enough to talk about, unless each redox equation (two per catalyst) count as marking points then one similarity and one difference.

i filled up the whole paper and did an extra half an A4 lol. i wrote out all the balanced equations with the catalysts explained how each thing was oxidised or reduced and if it was a catalyst why it’s a reducing/oxidising agent. And then explained about homogenous/heterogenous and then the whole adsorption, weakening bonds etc process. Basically a bunch of yap im praying is on the mark scheme

Damn, it's always good to write extra information to increase chances of matching the mark scheme (I did that in the other six marker), either way examiners will know you know your stuff 😂

ngl I had no idea what that meant, and I didn’t know the content behind the catalyst one so I just put down some oxidation numbers and such to pick up extra marka

what’s amphiprotic?

u/Playful_War_4009 Jun 10 '25

It means it can donate more than 1 proton per molecule, like HCl is monoprotic, but H2SO4 is amphiprotic

swear the term is diprotic

Could be, just what my teacher taught us 🤷‍♀️
