redox titration n entalpy change is comin

just a guess it is .

 

[RoOkaYya G]

for salt analysis it will be related to organic coz most of the recent questions are related to it
Its also quite possible 4 u to get a titration since in the june session there was 1.
best of luck

in every paper 3 theres a titration for chem dr

 

[abdul moeed rana]

you do that please
although no one is stopping us,more comments means more trophies for the owner of this ......
caant remeber that word
yesss thread

 

[RoOkaYya G]

im expecting a double indicator titration. since syllabus gonna change. they oughta do a nice closing ceremony

What's that ? :O

 

[RoOkaYya G]

What's that ? :O

u use 2 indicators for 1 titration. u dint knw?

 

[Bilal Khan]

u use 2 indicators for 1 titration. u dint knw?

I never did one .
For example ?

 

[emilyy]

in every paper 3 theres a titration for chem dr

its nt always the case dr.. check nov 2009 p3

 

[RoOkaYya G]

I never did one .
For example ?

never did?!
the most typical example is for iodine n sodium thiosulphate.
titrate with a solution in burette until the brown colour is discharge n the solution becomes yellow in the conical flask.
then add starch indicator (few drops)
then retitrate with the solutioon in burette.

well we give As n A2 together. so we always have 3 questioons. titration ,enthalpy and analysis.
where r u from?

ur right, even i give AS n A2 together, hwvr i'm jst stating the diffrnt possibilities.

where r u from? whch variant u give??
yeah but the example u gave is long back!! 2009!! cmon!
n now CIE wont be making us gifts dr. they r plannin to screw us up .so get ready
u tasted the sweet m1 paper on 17th? hows it?
see? CIE is really gonna screw us up. n for S2 students. they shld get ready. their paper gonna be nuclear bomb as well

hihi so this is called a double indicator titration kid

I am just a kid retaking in AS . :/

REtaking? y??

hmm...dw ull do good

 

[Bilal Khan]

REtaking? y??

hmm...dw ull do good

I got a C in chemistry ( although an A in practical ) .

I am just worried about the theory paper , coz the may one was bad . :/

 

[RoOkaYya G]

jst try do as many paper as u can. expecially p 4 coz they r weigh more. (congrats for ur practicals )

u r taking whch subjects?

I am giving only AS chemistry , so no paper 4 .

I am taking just chemistry .
