today i made a big mistake during lab.. in one of the steps.. i used the concentrate HCl acid instead of the aqueous HCl acid.. so..well.. since i am already half way through.. so juz continue la.. act a bit.. den later if cannot den get from friends.. i ask the teaching assistant(TA) how.. den she say juz improvish a bit and continue lor.. and so.. i have to add a lot of sodium bicarbonate to neutralise it.. haha.. and surprisingly.. i got the most yield!! haha..

afraid tt it might be wrong.. the TA help me to do the TLC chromotagraphy to check.. and turn out its very good.. haha.. no starting material at all.. woohoo!.. and guess what after tt.. the TA show the other TAs abt it and even ask me how i do.. haha.. i think they going to change the lab manual instruction.. haha.. all because of my mistake!! haha..
