you know. i studied for chemistry practical,
till i dreamt of me teaching myself the charge of Mg ion. wah so joke man. i know that ethanol is a reducing agent!! and when hydrogen peroxide liberates Oxygen gas Hydrogen peroxide acts as a reducing agent. haha wadeva lah.
okay well it went rather well i guess. GCE O level Chemistry Practical went rather well!! okay let me take u through the whole thing. well was glad to see the biurette and no thermometer when i entered. and heard some peeps saying that it was a colourless reagent.
well i so happy can. first one to achieve 'pop' sound in the lab. hmm okay. then erm glad that at least i got the acid correct this time.
Planning question seemed rather okay. even though i talked about taking both acids initially. then thought otherwise and cancelled quite abit. i think i was washing the conical flask or wad then some droplets of water landed on my page. so guess wad? the towel was convinently there, so wipe and.. SMUGE!!! my whole planning page got ink smuge lah so ugly.
ahh!! and u know wad, i forgot to mention to use the metal in 'excess'!! basic can!! i said use a 'magnesium strip of 2cm by 3cm..' okay doesnt matter now anyway.
then we come to QA. my solution T had no label! so i changed for another bottle. and the moment i opened it, i SPILLED THE SOLUTION all over the table. so i asked for another bottle, again. then the invigilator was like, "you're so troublesome!" okay well cant blame me right!! and the best part is, i didnt even use the new bottle of reagent she gave me, coz there was still some balance in the toppled bottle.
well i didnt know whether it was a brown ppt i saw in the last test. u know i wrote reddish-brown lah. coz everytime i wrote down wad i observed i got it wrong. well upon closer inspection at the stuff inside the test-tube. i decided to pour it out on the white tile, guess wad? i saw.. BROWN!! okay so i wrote brown instead, got it correct i guess. Thank God.
okay this is the best part.. for the last observation, i saw something like cream ppt. then i was like about to write cream ppt, coz Mr Won said we could and should if we saw that. then i recalled someone saying not to write Cream Ppt, well figured it had to be Miss Ong. i stared at the test-tube for a very long time okay. then recalled the basic technique of ppt detection.. pour it out, pour it away!! so i poured it on a white tile. i even used my finger to rub it. i still get cream ppt. and it so happened that my bench cloth had to be beside the white tile, and it had to touch the 'cream ppt'. so guess wad? i saw YELLOW on the bench cloth. so i happily wrote pale yellow. Thank God.
okay. well i got aluminium instead of zinc. duno why also. u know i wrote zinc initially and changed it to aluminium there after. Thank God. according to Mrs Lim and other schools, aluminium is correct.
heard that thursday's practical is not gonna be easy man. everyone's spotting like, vertical oscillation, pendulum, lens and heat. well u know last night i dreamt that lens was gonna come out, but i dreamt that it came out for chem prac instead. haha wadeva lah. go study esp those okay. and all the best for the rest of the papers.
Gonna be over.. SOON!!
