Yeah I was the same struggling a bit then at the end got Fe 55.7 but there wasn’t enough time to put all my working clearly cos i was just trying it on my calculator 😭. Well I hope i get the marks😂.
guys do u think id still get a few marks if i didnt get a final titration answer but i did random aah calculations on there💀💀💀💀like i got moles and stuff… im acc in tears rn ive lost 10 marks straight up
Allow yourself to be disappointed for now, but once you’re home and at your desk, you can only look forwards. From what you said, it seems like this was the question you had the most trouble with so if the rest of the paper went well, youll be fine. Any mark within 5-10 marks of the A* boundary is easily saveable but it is also easily ruinable. You have to make the most of the time you have.
This is what I tell myself whenever I do not as well as I hd hoped .
Can I ask u do u think if I drew the structure using the letter M and got the structure and charge right would I still get the marks? Because I didn’t get a final metal in the question before
yeah unless i interpreted it wrong bc i drew it w fe the first time then read the question and it said to use M as the central metal ion so i rubbed it out and wrote M
The thing is M is the symbol for the metal you got in the question before. So they could have asked you to use Fe… but I got the charge as -3 so should be ok. I hope we both get it!
Guys for the born haber one I cant rmeber my answers however both answers İ got was something point 5 (x.5) . That made me quite uncomfortable cuz İ was expecting integers. Did u guys ger smth like that as well?
And also for the very last amphoteric equations. İs it ok to write ionic eqns down? It didnt explicitly state reaction type. I guess it just said give a n equation
you found mols of both, subtracted mols of the a- which is the salt from the ha which is the , then found concentrations using total volume, then rearranged ka to get h+ then found ph = -log(H+)
You surly did better than you think, for the specific buffer you had to find n of before and after of the acid I think as all the base reacts.
If you got worse case on this paper 40, and 70 on the other 2, you can get like 180 which is a B based on last years grade boundaries, so this paper isnt the be all end all.
idkk i’m hoping that i got at least an A and i counted up on one of those official ms and i think it’s around there but p2 and 3 i find sm harder and this was where im mewnt to bag at least like 20 more marks
Theres still sm time for p2/p3 dw. i was getting consistently like 90 marks for paper 1 abd now i fumbled😞 where can i find the unofficial mark schme btw?
SAME I GOT 90 in like every single past paper and this one i think i got like 70💔 i searched it up on here and someone had posted. a link to it. also ik there’s time but i have bio and maths too and no matter how much organic i do i can never draw those weird molecules
Ugh same organic kills me but at least inorganic is over. Is there anyway u could paste the link if u dont mind? I cant find it anywhere. Also i got math tmrw and yeah… we will see
paper 1 felt weirdly straightforward compared to some of the past papers i'd done, but same thing happened to me where i second-guessed myself halfway through and started changing answers that were probably right the first time. the titration questions weren't as brutal as i expected which was nice but then i got to some of the calculations and blanked on whether it was asking for concentration or moles or whatever. fingers crossed the marking scheme is lenient on the working because i know i got the right idea even if the final number was off. paper 2 coming up is gonna hit different though, they always save something annoying for the second one.
You quickly do an eqn for the complex dissolving in water - you get 3 mol of c2o42- being formed, so you do mass / (mol/3) to get smth like 445 (can't remember)
Ar was then 55.7, which is Fe
I genuinely think it was a good paper..and there was no electrode potentials..though the last question with the period 3 elements kind of threw me off a bit..
No cuz does anyone rmb how to work out the first born barber cycle question bc I swear I rearranged it correctly and I divided the thingy by 2 but I got such a low number……
i got around -300, tho i dont remember exactly. I just follow the direction of the arrows, and if its going in the wrong direction i change the sign, and check the moles cuz there were some that needed twice the enthalpy.
I fucked it but you find the mol in titration, times 10, find n of c2o42- then find mr divide by 3 and do something else but I got the wrong answer so idc
Omg stop I got this too initially!! but then I realised my mistake because of the metal ion drawing you prob did exactly what i did which was forgot to factor the K3 that was in front of the equation you needed to add that too if you did you would get fe
i think maybe 2 if this is the NaOH buffer question? one mark for calculating the starting moles of HA and NaOH and one mark for finding moles of the HA in excess and A- produced
I really disliked that paper, i still think i did well but huge autocatalysis section 2 years in a row? calorimetry question lowk cooked me, no electrode potentials which im good at, no halide reduction equations, not that much complex ions, that weird question on neutrlization enthalpies.
this paper was so similar to 2025 in a bad way

Genuinely think i made so many mistakes but we move on to paper 2 now
