Chemistry trouble

[alexthekidd]

wow, i didnt even get as far as titration in chem... hah.. i quit after 5th form.. its mostly boringness to me... give me biology any day!

sorry i couldnt help mate!

Ah men to dropping chemistry after 5th Form AJ Give me History anyday

Oh sorry for not contributing anything, i'll hang my head in shame now

[flash]

nah i like the real sciences more :P, bios a girls subject .
usually chems pretty easy, but i seem to always make it harder for myself.

so everyone, ive tried to make a sealed cap for my pineapple juice instead of the whole grape juice, ill tell the results tomorrow and say if the seal holds up.

and no you wouldn't get wasted on it, you would have a very clean stomach though :P

biology is actually one of the more hard subjects... i mean... just the other day in my anatomy lecture we were going through the complexity of muscle cells and structure etc... it just gets smaller and smaller!! memorising that is a bitch... but we DO get to disect cool things like pigs trotters... i enjoyed that.. i should be a surgeon instead of a vet nurse....

mmm well, how did you seal it? and ill tell you how itll hold up... im good at that sort of thing... lol

[flash]

yeah i know, i was only joking bout the bio. just my mates are doing it this year and have to grow 200 plants :P

i cut a hole in the cap, and wraped that split black ruber around the cut and hot glue guned around the edge, then ill be puting in a rubber cork that lets u suck out air with a pump. if that doesnt work, im bringing the hot glue gun with me and gluing thdamn thing in :P

Will this get you pissed ?

Big splash of vodka will accelerate the chemical reactions. (at least in your head)

that seems solid enough to work actually.. it should be fine... as for the 200 plants.., thats REALLY GHEY! in my time in school and uni, ive done SOO much more exciting bio! lol...

I did the VitC test back a couple of years ago as well... just used various orange juices like freshup and just juice etc. Got some good results from that.

Can you put it into another bottle?

If you think chemistry sux, how can you get into biology? Biological processes don't happen by magic, it's all chemistry!

It's been years since I really did any titrations so take my advice with a grain of salt. With the titration could you not titrate the grape juice with DCPIP (dichlorophenolindophenol)? a 0.1% solution will react with ascorbic acid and form a blue solution when all the ascorbic acid's used up so you can tell how much ascorbic acid you had to begin with. The grape juice being coloured might make it difficult though. More info on it here anyway. http://www-saps.plantsci.cam.ac.uk/osmoweb/vitc.htm

Did you know that if one was to grasp the Trachea of a sheeps lung and blow into it they inflate and turn nice and pink again. Plus if some one squeezes them at the same time you can make Bagpipe sounds. My Army Adv Med 101 experience.

Can I just try it with the vodka.

Sculling vodka, AND blowing sheep....Damn!

[Curious_AJ]

hahaha, you certainly have a weird way of interpreting things tri boy....

[flash]

your not allowed to use different brands now, they said it became too easy or something. so now you need the exact same juice but test it at different time periods. i didnt want to change bottles but if myy makeshift sealer wont work ill put them into the wine bottles

that makes the whole grape juic look sooo much easier. might print that and take it to the teacher. but ill also bring the pineapple juice becaseu i know something gona go wrong with one of them :P
