hmm~ i'm still editing my blog.. i added my profile, added the comments function and change some of the design..
KK let talk about today's chem pract... Today we did QA(Qualitative Analysis) and it was quite a rush as we only had 1hour as the other 1 hour was fixed for VSEPR tutorials.. like last week.. i am again at the gas chamber there trying to wash away the stubborn yellow PPT stucking on my testtube with conc HCl!.. but it didn't seem very useful after 2 attempts... den i gave up and procedded to my QAs... i've always hated QA becoz of all the poisonous gas produced that we HAD TO test! adults talk abt exhaust fumes which contain CO2 and SO2 etc are harmful to the health and suchs..but here we are trying to detect the gas with our nose. no wonder my sec sch chem teacher told me chemist always die earlier...ok back to the chem pract. 1/2 out of the ard 8 test were all for us to test for SO2 gas and one of the test the pungent smell was so strong that i kept sneezing and coughing after smelling it. and it didn't end just like tis... the gas was continueously oozing out and even my friend 2 benches infront of me can smell it too..
