This week, the Grade 12 TOPS Chemistry class tackled titrations: learning about acid-base equilibrium, salt hydrolysis, buffer solutions, and more. Students performed multiple experimental trials using all sorts of indicators and substances such as THAM, otherwise known as C4H9O3NH2. Doing the labs definitely lifted everyone’s spirits: it was clear (like some titrated solutions) that no one was left feeling (bromothymol) blue! (Author: Allyson W.)
