Three shine in chem­istry con­test

Western Suburbs Weekly - - Western Opinion -

THREE Year 12 stu­dents from St Hilda’s Angli­can School for Girls were in their el­e­ment when they com­peted in a State chem­istry com­pe­ti­tion last month.

Lara Ed­mands, Faith Chow and Laura Peh won gold medals in the Na­tional Ti­tra­tion Stakes run by the Royal Aus­tralian Chem­i­cal In­sti­tute.

They com­pleted a com­plex ti­tra­tion at the com­pe­ti­tion and came first in WA and the rest of Aus­tralia with their to­tal scores.

Head of Sci­ence Ce­cilia Kin­sella said the school was “ab­so­lutely de­lighted” with the re­sult.

“We have pre­vi­ously had stu­dents reach the fi­nals but this is the first time we have taken out the State and na­tional ti­tles,” she said. “We are pas­sion­ate about chem­istry at St Hilda’s and it is won­der­ful to see the hard work of the girls and their teach­ers pay off.”

Ti­tra­tion is a chem­i­cal anal­y­sis tech­nique used to de­ter­mine the con­cen­tra­tion of an un­known so­lu­tion. Judg­ing is based on the val­ues each team re­ports and are ranked on their ac­cu­racy com­pared to the ac­tual con­cen­tra­tion.
