Dissociates into NH4+ which donates proton to water and there is B-L acid.

i showed that it reacts with OH to form NH3 and water which is basically showing the same thing

i think there's a mistake in their solution to 31, the graph is skewed in that scan so they accidentally drew the line down to 0.044 instead of 0.046

ye ik lmao i think whoever made these solutions basically was just speedrunning tf outta the exam but yeah it should be 0.046

It was the acetic acid and trichloroacetic acid question

that seems familiar but I dont remember the context of the question lmao

that seems familiar but I dont remember the context of the question lmao

Part (a) was finding Ka of dichloroacetic acid and part (b) was using gibbs energy and Ka values to explain the difference in strength of the acids

for the sols Q28 using bromine water doesnt CONFIRM that the compound is an alkene as alkynes also decolourise right? Wouldn't further testing be required to really CONFIRM its an alkene?

Here is Roy Fu's solutions (PEAK). This one is for the whole paper.

 

[SB257426]

does anyone have maybe like a soft copy of the entire paper?

 

[carrotsss]

PEAK solutions

 

[tywebb]

PEAK solutions

Yeah. The same ones I put in post#397. PEAK's is the same as Roy Fu's

 

[carrotsss]

Yeah. The same ones I put in post#397. PEAK's is the same as Roy Fu's

mb didn’t realise

 

[tywebb]

mb didn’t realise

That's OK. Maybe you didn't know PEAK's is the same as Roy Fu's.

 

[SadCeliac]

Tywebb is there a full paper scan yet? How did they do full solutions with the scuffed scan?

 

[tywebb]

How did they do full solutions with the scuffed scan?

They didn't. They probably just used a paper paper.

 

[carrotsss]

That's OK. Maybe you didn't know PEAK's is the same as Roy Fu's.

yeah I though Roy fu was just some persons solutions rather than PEAK because I hadn’t opened it

what do u think the band 6 cutoff will be?

 

[Adrian_jnader]

what do u think the band 6 cutoff will be?

I reckon a 95 raw if NESA is generous?

 

[Goldattacker40000]

I reckon a 95 raw if NESA is generous?

Nah I reckon 98 maybe.

 

[Adrian_jnader]

Nah I reckon 98 maybe.

Yeah that sounds about right. I had a mate Eric who got a raw 97 last year and ended up with an 89 final

 

[hb0623]

what do u think the band 6 cutoff will be?

Last year I think it was 85, will probably be similar to that

GUYS I DREW MY COMPOUNDS FOR THE 9 MARKER IN PENCIL

WILL IT STILL BE SCANNED???

PLEASE HELP

I'M ABOUT TO CRY

I THOUGHT I DID IT IN PEN
