What was the hardest thing u found in this paper?

 

[iSean97]

Is the question regarding :

(1) Inorganic Chemistry of Cu?
(2) Hydrolysis of Sucrose?

If it is it is the same paper for Paper 53 in Zone 4.
Quite easy and guided.
Those who will have trouble will be the first part of Question 1.

52 and 53 are totally different

 

[iSean97]

52 and 53 are totally different

Then my paper will be with Paper 51 then.
Because CIE always duplicate papers, but with the same code.

Well Paper 53 was quite easy

IT WAS SO EASY. Im worried about the threshold now.It'll probably be very high

And what about P1 dude?

what were ur answers to followings?
1) the very first question, why buffer is needed or sth like this
2) three appartus for measuring volume with the value of their size
3) effect of Vfinal - V

I am done with As.

2) three appartus for measuring volume with the value of their size
3) effect of Vfinal - V

for buffer i wrote, H+ ions are produced by the reaction so the pH would drop low, hence a buffer is needed to keep the pH constanr
apparatus I wrote 50c3 burette, 250 cm3 volumetric flask and third Im not sure about but I wrote conical flask 250cm3
and effect of V final? you mean of temperature? I wrote if temp is higher than 60, V will be higher than expected and vice versa

Hello peeps! What was ur order of rxn for the last part (i got 1st order)? And secondly wht did u guys answer for the question that asked that how accurate will be ur values be if temperature is raised to 60°C and what happens to the value of Vfinal-V?

1st order.
V will inccrease.
Vfinal - V decreases.

yeah the paper was quite easy. but almost all papaer 5s of previous years were also easy so iguess the A* treshold will still be around 20-22 like previous years.
Just out of curiosity how many marks out of 130 did u guys get at AS level

does ur answers match with mine?
There is no A* threshold.
I guess 83/130 (76%) b. was my As level rseult.

same answer
i explained that v will increase cuz mor ethanol or whatever chemical vapours will increase due to higher temp. this will increase V and the Vfin-V will decrease

madhavmk what was ur answer to first question, PH buffer thingy?
and also for 3 volume measurements with apparatus?
