On June 8, QHS will host students from other schools across the region for one of the NSW 2021 Royal Australian Chemical Institute - Titration competitions.

The NSW Schools Titration Competition is a quantitative analytical competition open to the state's students currently enrolled in senior chemistry studying towards the HSC.

"We have three teams of three students entering from QHS this year and look forward to hosting students from a range of schools in this highly-contested event," said QHS science teacher Peter Roberts.

Students compete in teams of three and, in ninety minutes, must complete a set of acid-base titrations to determine the unknown concentration of a weak acid.

The team's score will depend on the accuracy of the work of its members. The best score wins medals for the team.

They may then be invited to participate in the national competition later in the year. The competition is well aligned with the new chemistry syllabus.

Other universities and schools to host the competition include Western Sydney University, University of Sydney, Macquarie University, Knox Grammar School, University of Wollongong, and more.
