Vic Branch Titration Competition 2017 - 2nd Feb 17

INVITATION TO PARTICIPATE IN THE 2017 COMPETITION

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 competitions and this year we hope to break last years record for the number of students taking part. The overwhelming response to the competition in recent years has been 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. Detailed instructions are provided and should be given to all participants.

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.

Like last year, the rules of the competition have been changed slightly to put more emphasis on teamwork. In previous years, too often some members of a team have come quite close to the right result, but the team has been let down by others who, for example, have got the decimal point in the wrong place. This year, all students in a team will be responsible for determining the concentrations of all three alkali and acid solutions. Thus all three members of a team will work together to agree on measurements and calculations.

Schools will be required to report the results on-line.

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, usually to determine the concentration of an acidic material in a mixture of solids, again carrying out a series of titrations. 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:

There is no limit on the number of teams schools can sponsor.

The entry fee per team is $43.00

The closing date for entry is Friday 31 March, 2017

Once registered you will be sent the link to electronically submit your results and also your Instructions.

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 to the Victorian Office by Friday June 30 June, 2017 (the last day of Term).

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 chemicals 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.

Competition Rules and Prizes

RULES

Each Team must consist of three Members. Members of a team will be undertaking Year 10, 11 or 12 Chemistry. The members of any given team do not have to be all from the same class or year level.

Schools may enter as many teams as they wish. All entries, accompanied by the entry fee, must be received by 31 March, 2017.

The experimental procedure as written will be used.

The experimental work and calculations are to be performed within a two-hour period.

All result sheets are to be submitted Electronically by 30 June 2017.

Prizes will be awarded solely on the basis of results and returned by the specified date.

Arrangements for the delivery of the material will be made with each school organiser.

NATIONAL COMPETITION

The top 10% of teams in the Victorian competition will be selected for the National Finals, which will take place at schools in September, to determine the top school in Australia.

NOTE

If a team member from the State Competition is unable to compete in the National Finals, the school may substitute ONE team member only, provided that the School can sign a declaration that this is due to unforeseen circumstances.

PRIZES

All participating team members will be provided with a certificate signed by the Branch President.

Members of the top three teams in the State competition will receive gift vouchers and special certificates of commendation signed by the Branch President

Members of teams selected for the National Finals will receive special recognition and the top Victorian Team in the National Competition will hold the RACI Victorian Branch St Bernard’s College shield for one year.
