Given the following unknowns, identify each one, without using any other reagents or apparatus (other than test tubes). Rather interesting... but i got stuck after running out of ammonia [suans self :-(]
HCl | H2SO4 | CH3COOH | NaOH | NH3 | Pb(NO3)2 | KI | Na2CO3 | AgNO3 | Zn(NO3)2
Identify by smell
NH3
CH3COOH: vinegar smell
Identify by touch
NaOH: slippery
Mix NH3 with each sample
Pb(NO3)2: white ppt, insoluble in excess
AgNO3: light brown ppt
Zn(NO3)2: white ppt, soluble in excess
Mix Pb(NO3)2 with each unknown sample
KI: yellow ppt of PbI2
Test last 3 individually with each other
Na2CO3: Effervescence (CO2) with 2 other soln
Test last 2 remaining with AgNO3
HCl: White ppt (AgCl)
H2SO4: No rxn

The confluence of muggers
2 photos: (1) free period in class (actually, math relief, but that it is a free period still stands), (2) between chinese and chem CCTs.
Perhaps it is spurred by mutual revision and encouragement, or maybe stress relief (see esp the jokes in the 1st photo)... but whatever the case i didn't expect this.
Well... one day someone drew the Nike tick over a book, with "Just Mug It". This probably sums up everything - and it's going on our class jacket too.
It's eye-opening to be in the class that's the confluence of muggers in RI. Everyone (with a couple of notable exceptions) is a mugger to a relatively large extent. Class averages are the highest in the level for many subjects. Certain teachers spam us with 30% more beyond-syllabus info than other classes, and we hardly give them any problems (except once when a particular relief teacher walked out because we complained about his teaching, which was honestly bad).
Most are self-driven, and many are perfectionistic (obsessive-compulsive, even). Many have heavy CCA portfolios (we have 8 CCALs, the most among the sec 3 classes), and almost everyone is damn hardworking. And at the core most people are really, really nice. Notes fly around before exams, and MSN discussions over the past few days reveal that most seek to fulfill a higher purpose, something that would benefit others. Quite a large proportion are politically quite active with strong views. It's sad though that we have little time to interact.
In this class we don't go "Wah... you are a 4.0 mugger idiot", but instead, "Huh you didn't mug ah...wah how can? You going to GGXX... next time must mug harder hoh." In such an environment there is positive feedback: you become even more mugger. There is competition, but there is little hostility, and most people are quite humble. In many ways this is quite good - everyone gets better.
After exams everyone says "i'm going to die... ggxx" (that usually means "aiyah no more guarantee high 4.0). Some say "i'm going to fail", then get full marks. But actually i think these reveal deep insecurities that sometimes manifest themselves in episodes of emoness too. True it can be stressful e.g. a GPA of 3.5 would top some sec 3 classes, but it's near the bottom here, and since everyone's so perfectionistic and have so many commitments & portfolios we end up quite tired most of the time.
It's maybe a miracle how we all ended up in the same class. Sure, SE and GE were merged, but there is a new segregation: RA (Raffles Academy i.e. taking a subject at an advanced level, for those alien to it), and RA students tend to be grouped together for ease of timetabling. Well, some people's fears about being in a class of slackers are probably alleviated now. Elitism? Maybe, but probably not, in my judgement. Perhaps a lack of respect for slackers though.
So here it is, 3C 07. Renyan says "I wonder what we'll all end up doing in 20 years", and how we plan to fufill our "higher purposes" in 20 more. I do hope that we'll get to know each other even better over the coming year. It's a pity if we don't, because most people here are really nice.
