National Titration Challenge 2021


The RACI National Titration Challenge 2021 is designed to encourage secondary students who enjoy Chemistry, particularly its practical side, to develop their scientific skills and understanding. It provides students an opportunity to experience conducting an experiment in a laboratory environment at a local university in their state and the chance to compete at a national level. 

 

The RACI runs two titration competitions:

  • Regional Titration Competitions for high school students, which feed into the Australian National Titration Competition and
  • National Titration Challenge which is for teachers, science technicians and all those involved in the secondary or tertiary teaching of chemistry to students.

This website contains information on the National Titration Challenge.

What is the Titration experiment? 

Each team member performs two sets of acid-base titrations in order to determine the unknown concentration of a weak acid in a solution that is supplied to them. This weak acid is either ethanoic acid (commonly known as acetic acid) or oxalic acid. This acid is standardised against a solution of the strong base, sodium hydroxide, which is first standardised against a standard solution of an acid (either hydrochloric acid or oxalic acid).

How does the judging work? 

Judging is based on the values each team reports for the concentration of the 3 weak acid solutions. Teams are ranked on how close they get to the actual concentration for each acid solution.
These volumetric analyses vary slightly from state to state, but are equivalent in their requirements.

State Coordinators will invite the top 10% teams in each State to take part in the National Finals. The analysis for the finals is more demanding than the State competitions, and involves 2 accurately weighed samples of a weak solid acid, potassium hydrogen phthalate.

Results will be announced early in Term 4. All national finalists receive a gold or silver badge and a team plaque is awarded to outstanding teams.

How does the competition work?

  1. Register your school in the competition. (Prices vary in each state)
  2. Gather team/s of three students. Students can also enter for fun individually or in pairs but their results will not entered into the competition.
  3. Conduct the two Titration experiments in Term 2. Depending on your state, these can either be done at your school or at a local university. 2021 dates for each state are to be announced. 
  4. Top teams in each state will be invited to compete in the ANTC Finals held generally on a Saturday in Term 3 in each state. 2021 dates to be confirmed.
  5. Titration results will be sent to the national judging panel and the winners announced. 

 


What you’ll need to enter

  1. Space either in your school science laboratory or at a local university. University bookings can be made through this website. Dates will be released in Term 1 of 2021. 
  2. Apparatus. 1 x 25 or 50 mL burette , 1 x 20 or 25 mL pipette, 1 x 100 mL volumetric flask), 4 x 250 mL conical flask, 1 x 250 mL beaker 1 x 100 mL beaker, conical funnel, Pasteur pipettes, glass rod, wash bottle and supply of deionised/distilled water retort stand and clamp, filter stand, Result Sheet. 
    Note: It is recommended that each school bring their own apparatus if competing at a local university. 
  3. Materials for each team. 
Supply of filter papers, bottle of fresh phenolphthalein indicator solution and marking pens or labels.

Further information on the Apparatus and Materials required can be found in the Competition Rules.

Teacher Support 

We’ll be running a free webinar in 2021 for teachers registered in the ANTC on all aspects of conducting successful Titration experiments with practical tips and hints to support your students. 2021 dates to be announced.

Step 2. Titration Rinsing Glassware

Step 3. Titration Rinsing Pipette

Can you titrate as well as your students? Here’s your chance to find out

 

The RACI invites all Chemistry educators, Chemistry teachers and school/university laboratory technicians to take part in the "Titration Challenge".
See below for the information for the "2021 Titration Challenge".
Registrations for the competition will open early in Term 1, 2021.
Chemistry educators, teachers and laboratory technicians will participate as individuals rather than in teams. You do the analysis in your own time at your place of employment.
This is not competitive among teachers and laboratory technicians. Your results will remain confidential between yourself and the RACI National Titration Coordinator, and no results will be published on the website.
This is also an opportunity for you to encourage and mentor less experienced / new graduate Chemistry teachers and laboratory technicians at your institution to develop their titration skills in their own laboratory environment.
If you select to enter, you will have until 3pm on Friday 24 September 2021 to complete your analysis and submit your answer to the Australian National Titration Coordinator - Elaine Bergmann FRACI CChem Email: Titration@raci.org.au
