I never knew chem prac could be so fun!!!!!
KNN!
P.S (pre-script) : I'm very grumpy now, please leave my blog asap before you continue as I'll be swearing alot. Thank you for your attention.
--------------------------------------------------------------------
Ok, here goes.
Chem prac was exactly the same as 2003 JC2 BT2 paper. It was supposed to be smooth sailing cas I saw it before.
So, I titrated. (Thoughts in bracket.)
10 cm3
20 cm3 (almost there!!!)
30 cm3 (eh, why no change har?)
40 cm3 (WTF?!?)
50 cm3 (Ok, must be some mistake!!!!!)
So I wash everything, re-read the question, and titrated from the start again.
10 cm3
20 cm3 (dun even see a sign of colour change leh)
30 cm3 (still so PINK!!!! I hate pink!!!)
40 cm3 (OMG, again?)
50 cm3 (OK, must be something contaminated)
So I went to change my FA2. (stupid decision)
10, 20, 30, 40, 50 (all pink)
ARGHHHH!!!!! (Hence forth, brackets indicate comments, not thoughts)
Then I added phenolphthalein to FA2 (FA2 placed in beaker)
...
pink!
oh no!!!! erm, wait, that's good.
Then, the moment of truth!
I added phenolphthalein to the whole reagent bottle of FA1.
TADA!!!! PINK!!!
BINGO!!!!
pink flamingo, pink ostrich, pink ..., but pink phenolphthalein with HCl! OHA! we've got a seventh wonder here! Alkali HCl. Wait, that's possible, issit?
Anyway, I wasted half an hour like that.
managed to rush through the rest of the paper with out too much problems and I actually finished the paper.
Hahas. I still like the carbonate part.
I added HCl to FA5, then I smelt Cl2 gas.
Hmm, cannot deduce anything leh.
So, I took another bottle and add again.
Smelt it, hmm... Smells like coke.
Wait!!!!! Coke was high carbon dioxide content!!! (is it carbon dioxide?)
Invigilator:"pens down!"
(aiyah, no time, put CO2 lar.)
Invigilator:"I said pens down!!!!"
(no time to write about CaOH, just write CO3 2-)
So drama!
Pack up!!!!!
wash this, empty that, throw this, return that, ...
OK, let's check my list, what's missing?
1 100ml beaker... check
2 250ml beaker... check
3 conical fask... check
5 droppers... check
3 bloiling tube... check
6 testubes... check
burette... check
pipette... check
pipette filler... pipette filler? Oops, it's on the pipette.
(pull) cannot come out leh
(twist) not even an nm
(brute force, hahas, I was pissed enuf back then) Piak!
what happen?
look at finger, look at table, look at broken pipette. Oops...
Walk up to the lab tech...
YH: "Erm, excuse me."
Lab Tech: "You wait har."
YH(who finally feels the pain of the blood oozing from his finger) : "Eggs-kills-me!!!!"
LT: "I said wait lar."
YH: "..." (dotz, not smiley)
finally after what must have been years which was magnified into eternity by the pain on my finger, the Lab tech turns around ...
LT: "Yesh? May I help you?"
(Yesh you could, by turning around earlier)
YH: "Erm, where do I throw this?"
LT: "Aiyoh, why you so careless one har?"
YH: "Yar, I'm very sorry."
someone behind me: "excuse me."
LT turns away,
LT: "Yesh?"
YH: "Erm, I got a very deep cut."
crimsom blood was dripping from my hand like the spilt FA3 flowed freely from the reagent bottle into the measuring cylinder, but the Lab Tech definately didn't hear the sound of my blood flowing which m,ost probably sounded either like the gushing of a river or the ouching sound I've been making to get her attention.
YH(shouting): "PLEASE!!!!! EGGS-KILLS-ME!!!!!"
LT: "Aiyah, what lar? You go throw away the broken pipette and go back and pack lar, the next shift coming in!!!!"
She said all that without turning around.
YH: "..."
(tap tap tap)
LT finally turns around.
I raise up my blood drenched finger and showed it to her, expected to ask me where the brick red ppt came from.
LT: "Oh no! Your eally very careless leh!"
-------------------------------------------------------------------------------
You think that's the end?
No way, the saga continues... (not the saga seeds, you watch star wars, do you? yar, vadar strikes back)
My apologies, Star Wars episode 3 is Revenge of the sith, not Vadar strikes back.
Anyway, I saw Ms Oei, then she help me bandage up, ... bla bla bla ... (so nice)
Then I ask her if shd have extra time and she said yes, but now too late.
Abuden?!?
So she ask me to leave my particulars and wad not.
------------------------------------------------------------------------------------
Then later Ms Oei go into the LT when we were "locking up" to look for me.
hahas, then I must re-explain my situation and what the hell.
Sorry, very tired now, need to sleep. Took all the blood supplements I can find, iron tablets, chicken essence, ...
