Year 12 students Maria Ciubuc-Batcu, Bethany So and Rebecca Norvock qualified as a ‘team of excellence’ in the Regional RACI Titration at Griffith University and competed in the National RACI Titration competition held at the University of Queensland on Saturday 17 October 2015. Their results were of such accuracy that the team was highly commended and gained each of our students a ‘Silver’ Placing Plaque. Each student needed to standardise a standard alkali solution and use this to determine a contaminated unknown solid acid sample. This required the students to quantitatively clean up the samples before analysing the concentration of the acid. Our students were engaged in a three hour analytical Chemistry task and emerged very successfully.

“It was an honour to be a part of the QAHS National Titration Team, and so wonderful to have done well in this competition. In a way, we had been training since the school competition in Year 10, and this prepared us well for both the regional and the national level titrations. I look back on the time we spent working together to perfect our technique (and all the bad poetry reciting I did while mixing solutions) with great fondness and wish the best of luck to the future titration teams.” – Maria Ciubuc-Batcu

“Although our team experienced unexpected problems at the beginning of the titration, we helped each other to solve these problems and achieve these high results. Through this titration experience, I have learnt how to be more accurate and cautious about cleanliness in the laboratory. It was very rewarding for all of us to have received a silver plaque for our effort. This was one of my best memories from QAHS.”Bethany So

“To have the opportunity to compete at the Regional Competition and National Competition was a great learning experience and also very enjoyable. The experimental procedures were challenging and required a lot of preparation but being able to celebrate the successes with our team and Mr Cooper and to be able to represent QAHS at a National level is extremely rewarding. It was a fantastic experience and we have been fortunate to have learned so much this year by competing in the Titration Competitions.”Rebecca Norvock
