i'm afraid the the format may somehow change..
just like for my bio practicals, every year they have the same questions like asking for the errors, micrometry and blax3 but this time its completely different!!!
and they used to have 2 questions only but then this paper have 3!!  :o
so i really hope they don't change the format for chem prac  :-\
oops! ye hope so too! but was AS bio practical always 2 questions from 2007 - m2009??
in AS chem practicals it changes 2- 3 questions every session! and theres a pattern
anywayz i think wit 3questions the parts will b shorter & easier to solve  :P

hmmm
as theres a pattern of 2-3 questions with 2007-may2009 chem practicals - esp. paper 31
i think there will b 2questions this paper 33
isn't paper 31 comparable to paper33 & paper 32 to paper 34?

I am certain there will be three questions.

They throw in a surprise question after the titration and before the cation/anion identification tests. :X

when there are bubbles in a solution, is it necessarily CO2?

Can be any gas. Look at the gas tests. Usually ammonia, CO2, NO2, SO2 or H2. I think.

not necessarily but mostly it is...
Just see the chart on all paper 31s in page 12 -test for gases...that confirms it

they'll give the chart on paper33

I def, think they'll b 2questions with hard parts!! its a pattern they must b followin =P
