which point did u guys circle as wrong in the graph? and what was the concentration at the end?

i circled the 2nd one!!

 

[CaptainDanger]

Avoid discussing that please... You can after 24 hours...

 

[mehdi1028]

oh sorry!!

 

[littlecloud11]

yeah it was easy but i have a question... what was the final answer for the mole question? and are they gonna penalize if we give each answer correct to 3 s.f?

 

[Silent Hunter]

and is it appropriate to convert each answer of titration to 3-4 decimal places or we can give exact ones? and round off the final answer only? we wont be penalized for this or will we be?

 

[djaskari]

one cannot estimate wats going on in examiner's mind!! Sometimes he has given the answer rounded off in m.s. while in Oct09 n June09 he has written complete answers!!Dont worry

Alhamdulilah paper was too good!!
:good:

I messed up the graph as I didnt start from the origin..
All upcoming answers consequently wrong so need to work on P1 and P2 which is next to impossible due to only a one day gap... :bad: :fool: :x

 

[ronaldinho]

mine went ok..(((................
yar paper lenthy tha..(

 

[Jinkglex]

what do you mean from origin? we just had to join the points with 2 different lines didnt we?!

 

[littlecloud11]

we had to join the points but we had to start frm the origin @ jinkglex

ps. no one answered my question!! what was the final answer for the titration question ?? and will they penalize if the answers are given to 3 s.f ??

 

[tareen99]

does anyone remember the questions and answers to question 2?

Yes

 

[tanseer]

Hey guyz Aoa, can you plz tell me that the answer of final part of titration was 0. ...something..????
plz reply

 

[iceman]

LETS all hope for the best and pray for A* for everyone.......(though i made some careless mistakes :O:

qstn 2 was of electrolysis

dat was easy1

i dont think we were required to start it from origin.......

 

[iFuz]

@workaholic: u'll allowed marks of next marks upon e.c.f (error carried forward)
but marks of graph would be duducted

@Ayesha: we need to start that frm origin as when volume is 0 precipitate would not form thus 0 for both values!

 

[workaholic]

Thanks fasih for boosting my spirits.... I got A* in my mock and it wud be a hell lot upsetting if I dont get it in the O level

 

[Maleeha]

i didnt start it from the origin either.. :'(

 

[intelnehalem]

I don't think you should extrapolate the graph to the origin I don't think many people from my center did that lol
What was the concentration btw?
