Royal Australian Chemical Institute Gold Medal Winners

Chemistry Titration team

Year 12 Chemistry students participated in the National Royal Australian Chemical Institute (RACI) Competition. Congratulations to the State and National Gold Medal Team: Revania Pillay, Zahrah Azman and Isla Heath, who also took out the Excellence Award for their team and for the school.

The RACI titration competitions are designed to encourage those students who enjoy Chemistry, particularly its practical side, to develop their skills and to reward those who attain a high level of proficiency. All secondary schools are invited to compete in their local state-based competition. Entrants compete in teams of three.

In the competition, each team performed a simple acid-base titration exercise. Each team had to standardise a sodium hydroxide (NaOH) solution against a supplied hydrochloric acid (HCl) solution; and was then required to standardise three (3) acetic acid solutions with the sodium hydroxide solution. Judging was on the basis of the values each team reported for the titres and concentrations of the NaOH and acetic acid solutions. Teams were ranked on how close they got to the actual concentration.

The top teams in each State competition were put forward to represent their state in the National Finals. All national finalists received a gold or silver badge and a team plaque was awarded to outstanding teams.

Well done Revania, Zahrah and Isla.
