fuck have to retype this shit cos my post got so totally deleted la. fucking comp.
anywae, fucking bad day tdy tt is getting worst by the min. ok lest start fr the beginning.
titration was ok cos i had relli gd readings, 19.5, .7, .6, .6. all very close together and the ar of the unknown i calculated in the end was exactly 27.0. super nice. so ah duh i put aluminium was rite? exactly 27. den whoa shiok one of my best titrations. den when i come out i hear ppl telling me its sodium. wtf?? diff in ar is like 4 loh. kao. den i ask some of my frens from other schs they oso sae sodium. now chua lai cheng is saying sodium too. wtf??? n like my whole lab got aluminium la. including JOHN LEE. so now i relli duno wat to think. ok latest news i received from berd is tt we were supposed to get ar of aluminium got choose sodium cos it fits. wtf?? kana sai where got like tt one loh. tamade. den the stupid qa damn jia lat la. change so many colour. used up like 5-6 pieces of filter paper jus trying to see the colour of the damn precipitate n solution la. damn fucked up. den the extended question worst ah. they give like one eqn of this compound undergoing thermal decomposition to give co2 and h2o n come carbonate i tihnk. n den as of yet i have heard 3 diff ways of doing it la. firstly, measure mass. heat. measure mass after. den calculate frm there. havent relli run through the exact steps in my mind cos it seemed to cimple at first but now the more i think abt it the more i tihnk it might be correct la. kao. secondly, the one i did, put compound in conical flask, connect to gas syringe. heat den collect gas which shud be co2. measure volume den blah blah blah. tho i wrote it i tihnk its wrong cos there's just so much tt can go wrong. like gas is not at room temp n pressure cos of heating. (shit but actually u can let it cool rite? oh no.... i din put tt). den lastly the method which most ppl put which i think is correct is to heat the thing den titrate with acid cos acid-carbonate. sound the most correct i think. SHIIIIT. ok latest news received frm berd is tt the correct ans is collect gas. but i nvr tell them to let it cool!!! dieeeeee!!!!!! hopefully de "one step wrong rest wrong" way of marking is only clc's style n not cambridge's if not i'm screwed la. shieetttt... but relli tough loh. we practice so many extended qns and almost all are related to the question one loh. dis one TOTALLY isnt's loh. kaoz. how can liddat??? now i'm becoming more n more scared liao. they said last time tt our yr wud be the hardest cos its dragon yr n everything. i had kind of forgotten abt tt aft the prelims but now... it almost seems to be coming true. shit man. shit shit die die die.
