that's the one we've used all year. i was just reeeally confused before. i agree that this is probably the best for your average, standard titration

yep. our teacher's been pushing it all year, for physics too. mostly for the neatness factor, and the advantage of being able to see what you've already said. also, i think you said earlier not to put dots if you do it in point form, but i really don't think there's a problem with that. it's all...

*gulp* any help on that, helper?

wait.... what is this related to? what topic, general context etc???

don't worry mathock, you're not alone in being screwed. i have yet to actually go through the last half of shipwrecks cos it wasn't in our trial so i didn't make notes on it hsc online is a lifesaver though

"outline the role of a chemist employed in a named branch of industry or enterprise" hmmm, i guess that is to be interpreted kinda like "the responder" in english is. just a general, hypothetical chemist, as opposed to a particular one. but you can see how it's possible to interpret the other...

for q24, that'd be a titration, wouldn't it? 1. yes, you need to know why. they both discolourise because the UV light gives energy to the reaction with cyclohexAne, and the cyclohexene just does it in normal conditions

any experiments we've done neutralisation something about water quality/management? AAS named scientist + methods they employ biopolymer possiblity of use of ethanol as fuel there's heaps more, those just off the top of my head

i might be doing that too :) chem is not one of my best subjects though... i did ok throughout the year, and i'm ranked not too badly (which is good considering i go to a selective school), but i think i'm really going to stuff the exam up. i seem to have forgotten absolutely everything :( oh...

DAAVE + LSP = contradiction :S

does solutes = ions?

mathock, you are absolutely right. i got all mixed up. aargh my brain is fried :S

possibly... :o

algae are cyanobacteria... i'm not sure what that means though... good point o_O

phenopthylene (sp?) i believe

lol, yes, that's more correct. i was a bit limited in my answer, just thinking of the ones we usually do. also, with reference to titration curves, if you put the base in the burette, the curve is like reversed or something, ie starts at the top, rather than the bottom of the pH scale

uh... i'll try to find a pic of an example, but basically they show the change in the pH throughout the titration. they go flat, suddenly verical, then flat again. they often have questions where you have to pick the appropriate indicator. you want the indicator to have its range in the part...

acid in the burette, base in the flask. rince the burette and the pippette with their respective things. flask just rinsed with water.

sorry if this has been asked already or if there's a really obvious way of finding this out (in that case just point me in the right direction), but if it's not too much trouble, can someone post a list of all the acids and bases they expect us to know the formulae of? remember, you'd be...

i know this is offtopic and all, but paroissien, thanks to you, i have had that annoying "george's answering machine" song stuck in my head for the last several hours. and i fear it will stay there until the end of the chem exam tomorrow...
