Titration Competitions

Please note the following information:

The state coordinators will note the number of teams entered by each participating school, and will prepare an appropriate number of vials of standard i.e. known oxalic acid and of unknown oxalic acid samples to be posted or delivered to school offices. 

It is important to note on each of the vial labels, the volume of distilled water for the solid sample to be prepared as the titrant solution.

Further information on procedure, safety and calculations will be circulated by email from the state coordinators.

Additional information:

Again, the competition will run as it has for the last few years. Students compete in teams of three with each student standardising some sodium hydroxide solution with a known mass of potassium hydrogen phthalate (KHP) and then using their standardised solution to determine the mass of unknown sample of KHP. We will then process all orders and prepare samples to be shipped to schools prior to the start of Term 3. Once we receive orders we will ship samples to your school and you can complete the titrations at a convenient time in your calendar during the first 5 weeks of Term 3 (21^st of July to 22^nd August).
