The Royal Australian Chemical Institute (RACI) Victorian Branch invites your school to participate in the 2017 Titration Stakes Competition. Over 1000 students from Victorian schools participated in the 2016 competition, and this year we hope to break the record again for the number of students taking part. The overwhelming response to last year’s competition was very positive, and we are sure that your students will enjoy the experience.
All secondary schools in Victoria are invited to participate. The competition is open to students in years 10, 11 and 12. Students will work in groups of three and the experimental work will be carried out in school laboratories. Students may all be from the same year level, or may be from different year levels.
The scientific aim of the State competition is to determine the strength of a weak acid solution of unknown concentration by carrying out a series of acid-base titrations. Teams will be ranked on how close they get to the actual concentration.
By participating in the competition, students will be able to practise their laboratory skills using pipettes, burettes and other glassware, learn to recognise end-points and carry out simple calculations. A time limit of 2 hours is put on the exercise: 15 minutes to become familiarised with the equipment, laboratory safety equipment and exits, etc., 90 minutes to do the experiments and calculate the results, and 15 minutes at the end to tidy up.
The State competition will take place during Term 2. Top teams from the State Competition will go through to the National Competition which will take place later in the year. Prizes will be awarded to the top three teams in the State Competition and certificates of recognition will be sent to winning schools.
Schools going through to the National Competition will be required to carry out a further series of measurements. Victorian schools have been well represented in the National Competition in the past, and will be in competition with schools from across Australia. The top placed Victorian team in the National Competition will be awarded the St Bernard’s College shield.
Key information is as follows:
Solutions will be delivered to participating schools soon after the start of Term 2, so that the competition can be carried out at a time convenient for each school before the end of Term 2, with results to be submitted Electronically by June 30th, 2017 (the last day of Term 2).
Teams which are selected to take part in the National Competition, based on the results achieved at the State level, will be notified, and will receive the required solutions and instructions in September.
The RACI would like to acknowledge the ongoing support of Rowe Scientific in connection with the Titration Competition and recommends schools to consider Rowe for all their scientific laboratory needs.
