speedy gonzella! =) breezed through CHEMISTRY PRACTICAL today. wonderful! but, i still don't understand why the cation is aluminium although both tests dissolves in excess NAOH and ammonia to give a colourless solution. hmm, wierd. Nevertheless, it still doesn't affect me from targeting an A for chemistry. *giggles
oh well, i was pretty nervous when i first saw the apparatus laid on the lab bench. then, i quickly glance through the thin sheet of paper and saw QA questions. For a moment, i thought there was no VA! hah, but nah, after opening the booklet, those three tests were suppose to allow us to identify the unknown acid which so happens to be HYDROCHLORIC ACID ( HCL ). Initially, i wrote nitric acid as my first answer, but then again, there were no positive test to prove that is was nitric acid, cos my moist red litmus didn't turn blue. neither did i cough and choke on the horrible smell of ammonia gas. That's it, it's chloride ions. =) yay!
i was soooo lucky to have studied the notes MS YAM gave us on friday! it let me into understanding more about reducing and oxidising agent which really helps me a lot mans! *swoons* erm, actually i must also thank myself for studying for it right? YES, thankyou tingxuan! =) LOL. joke.
on the way out of school, my sis called. DAMNIT. i was so pissed. she went out with my maid, leaving no one else at home and expect me to wait like an idiot in front of the main door. !#$^&* i practically screamed at my maid and demanded her home to give me the keys. and yes, i slammed the phone at her. well done. =) they could at least have the decency to tell me beforehand so that i can bring my keys out. argh! whatever.
no school tmr. awww, i'm going to be so lonely at home. =( nobody's at home again. like SO FUN. anw, SATBS rocks ! hehe.
i'm off !
poof*
