Aww man, chinese looks set to be another paper that gets the average pass marks. Ah.
Wah, chem die sia, looks like gonna get deducted marks for experiment issues.
First time titration, too kan cheong spider then tritrate with putting methyol orange. Shit, saw her doing her rounds then realised the issue, so quickly spam methyol orange, end up whole solution very yellowish. I was staring at it, and thought: "wtf. Doesn't look right." Then she come over behind me, so I act act ask if calculating the amount of titrate used. After some time, still behind me, then I give up, crap number in table, and poured away the yellow solution. Then she started asking, "Oh ya, is anyone colourblind here?" Oh, sian diao.
Then, my the sucking thing got problem, can suck solution, but cannot eject solution. Wonder will I get deducted marks for removing the thing to release the solution from the pipette...
Lucky I remember to remove the funnels this time from the burette sia!
And my values for amount of titrate used is very weird. 1 is 24.7cm3, another 26.5cm3, and one more 27.0cm3. Wah sian diao, values of range so far away.
And I think my calculation of the equation stuff is correct.. Heh, only read the latest class test for SPA revision lah! And the formulas lor. Forgot how to get g/dm3, but i rmb something to do with the mol and mol/dm3 of the solution. So I just try out times, divide, with the two values I get until I got a pretty looking one, lol..
My upper right stomach muscle did a spasm on me while I was bathing. Ouch, wtf.
lousydude walked on the sunny side.
