Oh...I'm happy..

Want to know why?

Because....

C.h.e.m.i.s.t.r.y. P.r.a.c.t.i.c.a.l.I.s. O.v.e.r.!

Yes..it's over..not technically, still have to take the 'O' levels into consideration. Still, it's over! for now..*skips away in immense euphoria, lilt fashion*

"Lalalalalalala~"

Was i nervous before the examination?

Well, no. Because it seemed that my being was too small to occupy too many emotions at once. My monthly cramp had to come...at this un-timely...time. Too pain to be nervous wreck at the same time. Wait, pain isn't an emotion.

Anyhow, while the cramp with jaws like a pit bull terrier was gawning at my belly, I chided myself for not listening to my dear mommy. This is retribution, I tell you. Always pleading me to take the pills she buys, claiming that it would stop the cramp. Well, I didn't bother to take them, so here I am - suffering.

Oh, I digressed so much. Okay, back to chem prac. Surprisingly, I found it alright! Yes, Deborah actually finds CHEM PRAC ALRIGHT!!! Not dreaming am i? *pinches her cheek* "OucH!!" okay..not.

Yup. The titration and calculation of concentration of sulphuric acid was okay.

The QA was okay.( ignoring the fact that I wrote 'oxidising agent' thinking that they were asking for the role of acidified potassium manganate (VII), when in fact, they were asking for R which was a reducing agent !)

The identification of gas was really...energy sapping.

effervescence observed.

So i put moist litmus (blue and red) at the mouth of test tube. Blue turns red. Cancel ammonia gas.

Lighted splint and tried to make it extinguish with 'pop'. Failed. Not hydrogen gas.

Glowing splint does not relight. Not oxygen gas.

note: by this time, I'm already fretting..but no worries, it MUST be carbondioxide gas.

Pass gas evoled through CaOH...no white ppt...no reaction! how is this happening?!! Wait, must be not enough gas evolved. Acidify the solution some more. Pass gas evolved through CaOH..AGAIN... No white ppt!!!!

*frantically tries to calm herself down. carries on with the rest of the QA first*

Completed the whole paper, saved for the (stupid) identification-of-gas-evolved part.

Redo the whole part again and test for CO2...NO REACTION!!!!!!

Then, like a beam of sunshine through the misty fog, I figured it. TEST FOR SULPHUR DIOXIDE!!! (wah..very slow..took me so long to figure it out)

Acidified potassium dichromate (VI) Filter paper ready at hand. Put it at mouth of test-tube..wait..orange colour disappears..What??!!! No GREEN??!!

then..a few seconds later..while washing up the test tubes to redo the test, I noticed a tinge of greenish on the paper..confirmed it against the white tile and VIOLA!!! It is SULPHUR DIOXIDE!!

Well, time to hand in the paper..heaved a sigh of relief and bounced away to find Qin and Jess...

..expected to happily walk away from the lab, but they had to discuss about the paper and somehow lasped into depression-mode because they had some mistakes here and there..

"I'm gonna fail!" they wailed in unison...

Aye, IT'S OVER!!

luckily they did not mope for too long, (at least I know Qin did not cause she came over to watch 'Lemony Snickets and a series of unfortunate events' and had a great laugh)or else I would have been sucked into depression too..

to jess: eh, don't feel so upset. you still have your papers 1&2..*pats on her back*

to qin: I hope you are alright now...

to everyone else from 4e4: Good luck for tmr's physics prac! And don't forget to bring CCA Form!

I'm happy!!!

*suddenly recalls something..like an irritating stain that won't go away*

CRAP! Still have to study for CHINESE PRELIM!! WHY DID I CHOOSE TO RETAKE???!!! How can I put myself through the same misery after not touching the subject for 3 MONTHS??!!

ah yes, I recall now, I wanted to get an A1..I mean, WANTS. Still wants.

enjoy the free friday!(for those who aren't retaking..)*grumbles*

so much for being happy..
