Yesterday, I had my Practical (which means lab work) session. Everyone here calls it '
Prac', which sounds kinda weird (to me la). Haha...
We had to make
paracetamol, otherwise known as
Panadol !! ^-^
We mixed two chemicals (don't want type the names in case some people bored till fall asleep), heated
[加热] it on steam bath, put it in ice water to crystallize
[结晶], then filtered
[过滤] it. After that, we dissolve
[溶解] it
again, wait for it to crystallize
again, filter it
again to get purer crystals
[晶体].
After filtering the second time, I had some tiny white crystlas (Panadol o! people~) in my funnel
[漏斗]. We were supposed to pull out the vaccum hose
[真空软管] connected to the flask
[烧瓶] before removing the funnel on top. I couldn't pull out my vacuum hose!! So I asked the boy beside me to help me.
He DID pull it out. But my funnel went flying and the contents spilled out. {Sien...} My crystals spilled into some water. {更 sien...} My demonstrator helped me to save some but not much.
She told me "I'm afraid I have to take off some marks." {Sien sien sien...} Because we have to calculate the percentage yield
[纯度] using the mass
[质量] of our sample. Since my
panadol spilled, my calculations will not be accurate.
*Is anyone laughing at me while reading this?!?!? Sze Nee did when I told her on the phone. haha....* The boy apologised, of course. I don't blame him la~ It wasn't his fault. But my marks...... *sob-sob*
On my way home I bought ice-cream because I feel very down. When I got home, an accident had happened in front of my
lorong. There was an ambulance and police. Looks like an unlucky day~
That night, I talked with Sze Nee on the phone. It was nice to talk to someone back home. I felt really good after that phone call.
Before I went to bed, I realized another thing: I left my pen-drive at the Printing Centre in uni!! {VERY 'pek chek' now}
Anyone!! Just SHOOT me......
