Saturday 11 June, saw nine students from Years 11 and 12 participate in the Royal Australian Chemistry Institute (RACI) Titration Competition, held at Griffith University. The competition sees different schools from across our region come together in teams of three and face off to execute the most accurate titration. We thank RACI and Griffith University for their commitment and support to allow the event to continue this year.
Titration – commonplace procedure in analytical chemistry – is designed to determine the concentration of an unknown solution by neutralising it with a different solution of a known concentration. In this competition – where time is of the essence and precision is key – the procedure requires much deliberate practice to perfect. Our titration teams have spent many hours this year training during mornings before class and after school to perfect their titration skills.
Saturday's competition saw the scientific talent of QAHS' teams and individuals on full display, with two teams placing (1st and 4th) and Kaiser Lau achieving the most precise result for an individual in the competition, with a near perfect result. He has now achieved this for a second consecutive year.
Well done to the following students who represented the school with individual distinction:
Kaiser Lau, Stanley Wey, Anna Tian, Tanya Nagrani, Samuel Brown, Nitika Bethi, Hannah Provenzano, Ananya Garg and Edwin Lau.
Special mention needs to be made to the following students who produced some outstanding results that allowed the students to place 1st and 4th, presenting the QAHS teams the opportunity to proceed to the start finals of this exciting competition.
|Name||Percentage Error||Deviation from Actual result.||Award|
|Kaiser Lau||0.11%||2||High Distinction|
|Stanley Wey||0.23%||4||High Distinction|
We now look towards the Queensland State finals with competition dates and details yet to be announced.
