What do people think is the hardest paper out of F334? After the 2015 one obviously haha

ive just done the 2015 f334
I got 62 which is a solid B
3 marks off an A
Got all the equations wrong and most of the vanadium stuff 😑 Plus I forgot what combinatorial chemistry was 😂🙄

If they can put something like 5c in it

Can someone help me find out the relative number of protons for each of the proton environments?

Could someone explain buffers solutions to me place in terms of equilibrium?

Buffer solutions resist change in pH when a small amount of acid or alkali is added. This is because the buffer solution forms an equilibrium reaction.

Buffer solutions are a solution of weak acid or alkali and its constituent salt.

When acid is added, equilibrium position shifts to reduce the H+ concentration so to stop the pH decreasing (because more H+ means a smaller pH).

When alkali is added, the system tries to counteract the change by increasing the concentration of H+ so to stop the pH increasing.

I hope this isn't too jumbled :smile:

I am terrified for these exams :frown:

I feel like I know the stuff and have revised but when I do past papers I am still getting D/C. Anyone got any tips for exam technique as that's what I think is letting me down

I have also done all the past papers...

It's a hard exam.

F334 is a much harder exam than F335 imo. There is gonna be some tough slap in the face questions this year, I can feel it.

Wow....I just watched videos... and I printed out all the questions for WM , SS , TR MR and so I plan do them 2 or 3 times hopefully it will stick in... I hope they don't make it hard like the 2014 one
