hi all,
i've heard or noticed from patterns that we'll be seeing the following on the paper.....ethanoic acid,clove oil,soap,sodium thoisulfate titration,equilibrium and the winkler titration!anyone heard anything else??:cool:

grimloch

Didn't the Winkler titration come up last year?

I'd tend to agree with the organice ones though.

shane0312

Experiments probably will be a water of crystalisation.Maybe heat of neutalisation aswell.

-balancing a redox eqaution is likely.
-nuclear reactions
-Case study


Anyone have any others?

Winkler titration?

MB44

test for anions and equilibrium tests

Finding dissolved oxygen in water sample.

Volatile liquid molecular mass, anyone? Bloody chemistry.

Is everyone doing the industrial chemistry/atmospheric chem. potion?

niamhy101

the volatile liquid came up in 2003, but there are so few decent experiments to ask questions on it could easily come up again this year.

Yeah i'm doing Ammonia/atmos chem as the option, its a doddle!!!

are you sure about that winkler experiment, it did come up last year, i hope it doesn't come up again cos theres so much stuff to remember in it!!!

thegreenfairy

yeah sorry winkler was a mistake!:( oops...anyway i'm dreading chemistry!!!anyone any good cramming tips?!

ya im doin that aswell and its piss......I cant wait for chemistry aswell as physics and accounting;)

heya. just wunders if any1 has ne more tips????????

i think i may have a few but narrow it down to a particular topic/s and il be happy to share them

Just in general, what experiments, likely long questions etc.

well i cant say what experiments cos to be honest im doing them ALL equally as well..........
there are certain topics up every year so by covering them it wont be a bad start.....eg equalibrium and heats of reactions.....

I hate this - I hate having chemistry after this weekend! im so distracted! i just cant study!! uhh! I hate it!! HELP!!any tips for not watchin tv, avoiding going out and the internet? im so lost and I hate looking at all that I have to do!

I know how you feel. Couldn't go anywhere today cos I had to study chemistry though all I did was look through the definitions, test for anions and some organic stuff. At about three I was so bored I figured I'd go on the computer for half an hour to reduce my boredom. Haven't studied since.

To force yourself to study I recommend chaining your leg to the desk so that no matter how much you want to, you can't avoid your studies. Which reminds me, could someone bring me some food or water? I threw the key across the room and now I'm kinda stuck.

haha brilliant!wel stil have failed to get into the swing of things but at least im smiling now

maggie_cork

does anyone know what is likely to come out of these =

will washing soda exp come?
test for anions?
volatile liquid exp?
water of crystallisation ( Na2CO3xH2O)?
iron tablet?
Bleach?
Clove oil?
Soap?

Test for anions can come up on Q3 or Q4 and sometimes theyll manage to put it in somewhere else aswell, so ur always safer knowin that anyway. Clove oil, water of crystalization and bleach seem to be cropping up in alot of predictions. Anyone else know about the rest??

MKay

Also, whats evryone thats doin the option thinkin, NH3 manufacture or atmospheric???

I'm doing MgO manufacture. Its the only case study that still exists today.

L.W

is it possible to get away with not learning any equations eg the equilibrium rxns, electrochemistry and the oxidation/reduction rxns? oh and the tests for anions i find it impossible to learn wat goes where. i have to learn EVERYTHING and i mean EVERYTHING tomorrow and tues morn am so screwed. ive heard the water of crystallisation expt is goin to come up frm 3 different sources(not incl here)

d4gurl

Haha me to!I shud really get of the interenet!grr!!YAY SUMMER STARTES TOMORROW!!IM SOOOOOOOOO EXCITED!! that is why I dnt want to study!! AHH back to electrochemistry....

i'm leaving electrochemistry out...it's easy enough but i just hate it!!!

thegreenfairy

i .know.nothing...help!!!!

d4gurl

U wil be fine!I still have all of organic to do and titrations and water! My advice cover your organic, bonding, water, titrations and all the experiments - u shud be coverd

helles belles

ok i got this from a friend of a friend. This is NOT from the tute. but it seems a fairly good indication of what to cram

q1. % H2O Na2CO3
I2 v. S2O3
% hypo in bleach

q2. ethanoic acid prep
clove oil
heat of neutralisation
chromatography

q3. flame tests/anion tests
redox rxns

q4. various

q5.atomic structure
electronegativity
VSEPRT

q.6 organic
heat changes/thermo+ fuels

q7. rate of reaction
cat converter/particle size and conc/catalyst

q8.organic
rxn scheme and mechanism

q9.ph
H20
Acid/bases

q10. a)equilibrium
b)spectra
c)stoichiometry

q11.a) radioactivity
b)%yield
c)option

hope it helps

d4gurl

That would be a lovely paper!! Sigh Im guessing an unpredictable sh!it of a paper though!stil have al of organic and titrations and water to do!im gettn no where

goodgod3rd

thats pretty much what our lil (big big) teach told us, in the hills

hes almost alwats 50% right on his exps.... :P eveyr year#

i'm putting my uttermost faith in you!!

niamhy101

ok i probably sound completely stupid but what the hell are rxns? redox equations?

porn_star

ok
you better be right
lol
jk
thanks though
this is going to be a long night
