WITH just 90 minutes on the clock, three Lockyer District High School students began working on their titration projects.
They were up against a number of schools from the region, along with another Lockyer high school team at the National Titration Competition.
Monique Jeffs, Louisa Webster and Tara Reinke had only just started learning about titration during their Year 12 chemistry classes.
With limited practice, the three students worked the concentration of an acid by dripping a base substance until their indicator turned pink.
Each student had a slightly different concentration to work with.
But they never expected to win the competition.
“It all stemmed from someone doing titration as an experiment for an assignment,” Monique said.
“Louisa and I had never done titration before so we practised for two days prior during our lunch hours.”
“We hadn’t been in that sort of competition before and we weren’t expecting to win.”
After claiming honours at the regional level, the Year 12 girls are now eligible to compete at the state finals in October.
“It wasn’t very nerve-wracking because we didn’t expect to win,” Louisa said.
It’s the first time in a number of years that the Lockyer District High School has entered any teams in the competition.
Year 12 chemistry teacher Christine Robb said the competition demonstrated a good test of attention to detail, accuracy and precision.
“As the girls said, we hadn’t entered the competition for a long time and were really attending for the experience more than anything,” Ms Robb said.
“The students have currently being studying titration, so the competition fitted in well.”
