Just wondering out of curiosity where other people are up to in class in terms of the topic you are doing.
We just finished chromatography and moving onto spectroscopy.
-
We just finished chromatography and started spectroscopy.
-
Onto last topic of spectroscopy, mass spec.
-
Isn't NMR last?
-
We're doing AAS at the moment. I think we're a bit behind...
-
Did you guys do the sac1 for outcome 1-analytical techniques
-
Did you guys do the sac1 for outcome 1-analytical techniques
I'm finishing that SAC on Friday with a test. We've done AAS and we're yet to start the other spectroscopy stuff.
-
my class is still doing volumetric analysis, but I am up to chapter 10 in heinemann, which i think is reaction of organic molecules.
-
UV-spectroscopy :) very confusing.... i cant wait to get to chpt 12 and 13 (bio) woot woot....shit memories though...
-

Wow you work quite fast.
-
Starting on spectroscopy... we have a sac on chromatography and AES and AAS
-
almost done chromatography, sac on it is next term tho -_-
-
finished chroma today and started Spectroscopy, we started AAS.
we finished our Volumetric-gravimetric Sac two weeks ago....with quite a happy mark might I add :D

not really, plus i need to go back through UV/Vis Spec, NMR Spec and Colourimetry, i found them somewhat confusing!
i did all the questions on them but not really confident, especially for NMR!

Same. We're up to chap 10. just finished nine.

^ we have just finished covering acid/base and redox. we have our gravimetric and volumetric sac over the next two weeks. we are going so slow!
-
We're working on Chapter 5: Redox, but I'm working through Chapter 10, all those confusing organic pathways. I also need to re-look over all the Spectroscopy stuff :(
^ we have just finished covering acid/base and redox. we have our gravimetric and volumetric sac over the next two weeks. we are going so slow!
Wow, my class is exactly where you're at, lol. :)
-
Hmm being up to redox might be a bit too slow? I mean you gotta do like the rest of the stuff a few weeks prior to the end of term 2 if you think about it and term 1 is about to end.
-

Yeah, we're going a little too slow, I think. But hopefully everything will work out :)
-
do you guys have any holiday classes that will be running in your school?
-
We're up to chromatography... but apparently he was very disappointed with the SAC and people not knowing n=c*v and other basic things like that...so we've gone back to gravimetric and volumetric.
-
do you guys have any holiday classes that will be running in your school?
Nope, but our SAC is in the holidays.
-
do you guys have any holiday classes that will be running in your school?
Yeah, one three hour class. Weird thing, first time I've even come across the concept...

Wow, my class is exactly where you're at, lol. :)
same. spectroscopy and chromatography are really important and difficult concepts to grasp, so the clever people at heinemann decide that they will be very vague on those two topics and only give them a chapter each, whilst they waste like 6 chapters on repetitive year 11 crap.
anyone care to explain the difference between UV/Vis Spec and colourimetry?
i have no idea how they are different, unless colourimetry only uses visible light and can't select an optimal wavelength...
-
do you guys have any holiday classes that will be running in your school?
nah, except for bio because we only get one week holiday as that class is only 3 hrs 15 mins a week vs. all my other classes which are 3 hrs 30 mins each week...
-
You have like 1 class 3hr 30min a week?
-
You have like 1 class 3hr 30min a week?
yeah, usually with 30 min break though, so it's only really 3 hours :)
-
Damn, that's awesome so then you can be switched on an focused straight 3 hrs instead of wasting the 1st 10 minutes of every period to start tuning in lol

Ugh yes, Heinemann is so dodgy with explaining chromatography/spectroscopy. I'm reading through those chapters in the Jacaranda book and it's becoming clearer.
Pretty sure colorimetry shines the complementary colour through the solution and absorbance is read, but multiple substances in the solution could be the same colour so it's not very usefull unless the sample is completely pure. UV-VIS chooses a frequency from a substance’s spectrum and measures the radiation absorbed at this particular frequency.

thanks for clearing that up. :)
so is the jacaranda book good?
maybe i should get it....

It's more simple and easier to read so it's good to reinforce concepts.
I uploaded the book a while back and it should be floating around somewhere.

We did chapters 1 to 5 over the holidays, Started chromatography on first day, went on to mass spec/IF/nmr all that jazz now we're halfway through organic chem (chapter 12 in heinnemann)

Yeah you're right (: they both work off the exact same concept except UV vis is used for colourless substances

thanks. heinemann doesn't even mention it haha! also, did you by any chance make a donation to douchies biology podcast lol. he was thanking someone named tezza for making a donation...
and i'll have a look for it minilunchbox, much appreciated :)
-
ROFL yeah i did LOL
which podcast was it? i havent had the chance to listen yet
-
the glucose one. it's the most recent.
i feel inspired haha. that was a really cool thing to do :)
-
Haha yeahh, he pays hundreds for what he does and spends so many hours for these podcasts and he's been doing it for years. He told me he doesnt care, he just wanted more people to take advantage of these podcasts and enjoy biology.
He deserved it more than anyone i reckon ;D
Oh yeah, we did our analytical chem sac at VSECC today, got to use AAS, UV-Vis and GLC machine ;D
-
We're doing AAS at the moment. I think we're a bit behind...
Same here....
-
We're not even doing AAS...
We're at the very start of chromotography
-

Where did you go? we did ours at UniMelb, all we got to use was UV-Vis and our experiment was an epic failure. Our sample solutions absorbance fell like 10 times above the calibration curve haha!

ROFL! We went to Strathmore College VSECC to do ours.
Farr our UV-Vis was completely opposite lolol. The correlation coefficient (r) of our calibration curve was like .9978 or something aha.
You got msn stone?
-
You guys went on a chem excursion :o
-
Yeah :/ costed us 50 bucks also :/
50 dollars to do a sac and a whole day of chem zzz
-
We're going latrobe uni next week to have a look at the instruments, cost us 25 dollars....
-
so...has anyone here started doing practice exams?
-

Same. It was... not very exciting.
-
^ unless you find looking at a series of grey boxes stimulating :P
-
oh...I was looking forward to it!
-
Did you guys do the sac1 for outcome 1-analytical techniques
I'm finishing that SAC on Friday with a test. We've done AAS and we're yet to start the other spectroscopy stuff.
How did you go on the test??
-
OH wow its so simular XD
well i have a chem exccursion to VU on the first day of holidays at VU weribee( very uber far away) and i might get lost which most lilely will happen :( but i have to go but its free :3
-
Just finished the third practical of our SAC which was a spectroscopy analysis of fertilizer.
Got the final write up next wednesday and will have hopefully finished spectro and chromotography by then

finishing the course by friday hopefully

were up to chapter 11 cause we kind of started unit 3 and 4 last year
