i honestly have no idea, idek why i hate mod 6 sm i think i just suck with calculations for it

nah I get that, honestly repetition is the only thing that rlly works for titrations - though I know a lot of people who draw diagrams of the procedure to help with the logic of the calculations (like for pre-dilution and all that) and that seems to work

this might be the year they give us a chunky ass conductometric titration or titration curve to analyse tho and i lack the coherency to explain thos properly so might be fucked

lowkey ion tests are easy as fuck like its just common sense if smth gonna precipitate or not. if u need to figure out the colours and for some reason its not obvious to use just apply crystal field theory lmfao how u guys panicking. the hardest part is if they do a year 11 assumed knowledge recall and use galvanic cells to introduce pourbaix diagrams and then u gotta use it to find concentration of buffer systems eg

this q was in my school's trial was so fucked only 2 ppl got it right most got 0

Hey I remember seeing that question! Honestly this question isn't even that bad it's kind of intuitive after all. My good friend was one of the pupils who got it correct and was surprised more people didn't get it right, especially since it's mostly just year 11 chemistry, adding with some mod 5 / 6 concepts. Particularly since the bicarbonate buffer is literally mentioned in syllabus. Very nice question though!

ikr! hoping they chuck smth like that in the exam this year would def weed out the rote learners and actually make for a nice paper

common sense how though?? we were just given a flow chart I don't see any world where precipitate formation is common sense if there is an intuitive explanation for it feel free to link something idk

Also not taught crystal field theory, idk what extent you get taught content for chem in school/learn it in your free time but I know my school just teaches enough to suffice with the hsc syllabus/hsc style questions which means the content is usually simplified to a hsc expected level of knowledge

unfortunately i am a rote learner for chem bc i simply dont have time to look over everything and ive just been doing pastpapers

could u send solutions plss

mod 8 is the hardest imo. especially ion identification and stuff like that.

ions arent hard just a lot to memorise

yeahh I wouldn't be suprised if they give us one of those find the stoicheometry from the calibration curve or about how one of the spectroscopy machines function, could also give a rlly chunky m7/m8 combo (like last year but more writing) combining an organic synthesis pathway + asking us to validate that the reaction(s) has occured using spectras/functional group testing

Stoichiometry from calibration curve? Is that even in the syllabus? My school NEVER taught me this

 

[Pac574]

Wait we need to know everything from year 11? Like galvanic cells

nah there's no explicit year 11 content pretty sure, its more application of stuff and skills

 

[ManifestationIsKey]

It is for colorimetry and finding the stoichiometry for complex ions

yeah it's in the syllabus, or well it's in 2019 sample questions for mod 8 so kinda in the syllabus at least. See Mod 8 – Question 13, highly recommend doing it since they haven't tested a similar question yet

nah it's assumed knowledge, I've seen gibbs free calculations for determining spontaneity of non equilibrium reaction (m5 - combustion, photosynthesis) in my school's past trial papers but hasn't appeared in the HSC outside of the m5 syllabus

Thats in the m5 syllabus so they could test it but i doubt yr 11 content will be of high priority

You guys think this year will be a hard paper? Since last year was fairly easy

I THINK (JUST A THOUGHT):
2019 and 2020 same exam writers
2021 and 2022 same exam writers
2023 and 2024 same exams writers (hopefully it is fairly easy as well)

whats the best way to memorise reaction pathways

You can't memorise reaction pathways. You just have to know.

i saw there was a gas law question in last year's paper with the PV formula but thats on the reference sheet so you're all good there
there better not be any galvanic cells tho omg
