Did anyone do it? If so, how'd you go?

 

[comfortable]

yeah ive done it...and...yeah...our school didnt go too well james ruse got all the places! id advice u to bring ur own equipment coz they supply dodgy stuff and yeah...its pretty fun...

 

[steph@nie]

We did it today... and we broke 3 burettes, all our own.
One, the girl had it too lose and it broke, so my teacher put it in and she did it too hard so it imploded. So the angry man at Macquarie Uni put it in and he broke it too! My Chem teacher was not happy.
My school got 3 out of the 6 places, and my team came second

 

[steph@nie]

the winners at ours, Macquarie Uni, got 14 and we got 30...

we were in shock because we changed our titres n stuff.. so yehh

 

[aloquacious]

I think a score of 1 is 50% luck, in local comp a team from my school last year got a score of 4 i think, they were like....wtf..

yea well the shore guys had their results to like 2dp and the equipment was only accurate/marked to one dp

that is for example if the sample took 24.5ml to neutralise they would some how have like 24.53 or something
i mean i can understand 24.55 but that had like 0.03 and 0.04 and stuff....

and since they hosted it that had like better equipment
well thats what i'm sticking by anyway

 

[TheKing]

and plus i was given a 20ml pippette instead of a 25mL....
less volume that i titred against therefore less accurate....
dodgy privos

We did ours at UWS camobelltown hehe my friends came first! (I go girraween) they got 29 m team got 53 n yeh it was OK except for tha fact that i somehow managed to get a huge puddle of NaOH on tha floor n all over my front! *sob*

I was in the Shore team that came first, with a combined error of 1 =). I don't mean to brag, but a score of zero can be easily achieved without luck, it just requires sufficient practice. I haven't actually studied the uncertainty analysis of this particular experiment, however, scores of 0--1 are routinely achieved at Shore.
