Nope.

Obviously there will be 3 questions.

One on titration
Second on the identification of cations/anions
Third: SURPRISE :o

gl

I too have my exam a day after tomorrow.

im not really sure of my sources but i heard that the second question is about dehydration of salts(refer may/jun 2002)
and the third question is about qualitative analysis of course but something to do with organic chemistry........no reaction kinetics or thermo chemistry.......this is for paper 33!!!! good luck

I do not believe that we will have anything to do with organic compounds in our AS exam tomorrow. :S

i strongly encouraged u to read organic compounds because ethanol is present as a reagent in the exam lab.

if it's not for QA it can be asked in titration, so u should note the colour changes.

and about the crucibles, yes they are present on the exam lab for paper 33.

there's no purpose of providing a crucible (which is rarely used) if it don't have any function in the questions.

Thanks a lot for posting Pravin, but I had already finished my practical by then.

Alhamdulillah my paper went really well.

Good Luck for the next exams guys! ;D
