NT Titration Competition 2023

 

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 NT Regional Titration Competition.

 

About the Competition

 

Schools are invited to enter teams from Grades 11 and 12 in the NT Titration Competition.

The aim of the competition is to encourage students who enjoy Chemistry - especially practical Chemistry - and to recognise proficiency.  Leading teams in the NT Competition are eligible to enter the Finals of the National Competition, to be held during term 3 at CDU Casuarina Campus (Yellow 2 lab 2 , 3 and 4) – Saturday 9th September 2023, 9.30am to 12.30pm.


Preliminary comp: $18 /team and $10 postage /school if posting requested (else schools will pick up the chemicals from CDU on the set date and time below). There is no additional cost to students who are succesful in gaining a place in the National Finals.

Due date for schools to enter teams (by emailing the entry form to coordinator) - Monday 14 August 2023. Enter here.

Entry form for the 2023 NT Titration Competition should be requested from and emailed to [email protected]

Schools to collect samples on Wednesday 23 August between 10am - 12 noon or 3pm - 5pm from Yellow 2 Lab 2 at Casuarina Campus, CDU

Entry fee is to be paid online before the collection of samples on 23 August or before samples will be posted out.

Preliminary competition results to be emailed to the coordinator - no later than 5pm on Friday 25 August

For all teams competing in the NT competition, the analysis to be conducted is as follows:

"The analysis to be conducted involves preparation of a standard solution of potassium hydrogen phthalate (KHP) (provided), standardisation of a solution of NaOH, and titration of a second sample of KHP. Judging is on the basis of the values reported for the amount of KHP in the Unknown Sample."

There are Titration training videos available on the RACI Titration homepage.

 

Awards:                                  

  • All finalists get a Certificate and a medallion, gold or silver.
  • The gold medallion is awarded on individual excellence, not to a team. To gain a gold medal, the analyst must come within 1% of the true value for the sample.

Samples we will provide per team:

3 vials with known amount of KHP (0.3-0.5g)

3 vials with unknown amount of KHP

 

Since there is no limitation of space, you can enter as many teams as you want and we will supply the samples in vials based on teams entered (and fee paid). A flat $10 perschool will be charged if you want the samples to be posted to you.
