Log 2 – Review HW 3 – Demo 4 – pH Indicator Activity Today’s Goal: Students will be able to analyze pH indicators to determine the acidity or basicity of a solution. Homework • pH Indicators • If absent Fri (5/25), make up Quiz 18 by TOMORROW! • If absent Tue (5/22), make up Acid Base Lab by TOMORROW! • ALL work is due TOMORROW!
pH Indicators! • What is a pH indicator? • A compound that is used to determine a pH change of a solution. • How do indicators work? • Indicators change color when the concentration of H+ or OH- ions changes. The chemical compounds form new compounds with the ions with different colors.
