Yeah, done practical yesterday. Very messed up! Firstly, We, Cuer and me, mistook NaOH as HCL. But that cannot be blame what, both solution are colourless. Secondly, we forgot to rinse the apparatus/ pipette/burette(?) before using, thus have to redo again. .___. Thirdly, The bloody solution was contaminated for dk what reason. Out of 4-5 times, we succeeded once. :D But got a wrong reading. The practical is on Titration thingy, have to mix Phenolphthalein with HCL to make it pinkish, after that put in NaOH drop by drop until it became colourless, which takes forever. But damn cool, I like the pink colour. It look like some cocktails. HAHAH! Nevermind, next time will be better. (: |
