Help… for the first page… most of the calculations for ph we don’t have to find a new volume and work that way but for the second page we do, why’s this?? How would I know tomorrow in the exam what to do When do I know that I need to find new volume??
bro i struggle with this too and nothings helping 😭 i’m going through machemguy but it’s not clicking. someone told me yesterday that the easiest way to do buffers is just learn the steps, there’s no point understanding it esp this late
oh wait i see it, on the first page the solutions all add to 1000cm3 so 1dm3 but on the second page they don’t do it’s got something to do with that. sorry i can’t help anymore than that 😭

yeah i do ocr 😭 i’m literally getting like in the 50s per paper and buffers transition and the electrode potentials is my downfall fr. Good luck to you too, looks like we’re gonna need it fr. The machemguy explained buffers really well tbh, like you eventually end up getting it, also on pmt ocr recourses are so bad, if you go onto the aqa chem section and go on physical II they do model answers there on buffers and that really helped me understand the why a bit better
