How was it? In which solution FA9 or FA10 the NO2 gas was released?

The practicals were lengthy so I made some silly blunders

 

[iSean97]

Well I heard from friends it was FA9.

I didn't went through this paper.

Can anyone tell me the titration reading? What was metal M. If our volume of gas is wrong then will I get ecf?

titration reading was around 25,well it is different in different labs.The practical supervisors also attempts the practicals and gives his readings too usually the supervisor is your chemistry teacher ask him about the reading ,i guess the range is +- 1cm^3 from his .
M was K for me cause i had the Mr of about 135 and the gas collected was about 190cm^3 with .98grams of solid, my mates had similar reading so i am not so worried.
ECF in titration is given idk about gas collection.

it was hard and lengthy. Messed up both salts and gas collection

 

[lillyrk]

What was ur titration value

 

[HELLNO]

How was V31!!!

 

[techgeek]

What was ur titration value

got titre of 26.8 but it's different everywhere
messed up in both salt question and anion testing remained incomplete because I ran out of time
wasn't hard but too lengthy

same happened with me. i left 7 marks incomplete in last question. But if Manage to do good in Mcqs then there is no problem at all. just relax..and do as many paper 1 as you can.

yes someone told me, they had D in paper 33 but still overall got an A, because it really has a very low weightage. So it won't be of much impact at least we can hope

have you saw this before paper? almost was same

NO I didn't see that before but we had no enthalpy changes and other things it contain are which appear in every paper like titration and improvements and salt analysis xD , isn't it?
but yeah Oraganic Chemistry part sure came up

 

[Qaussain]

That take my time,Last Question barely i done it just writing the obervations,not performing it.
