Block April 15-16Due today: Light and energy worksheets and POGILObjectives: Flame testHomework: • Finish light and energy test review due Friday (day of test)• Study for test!!DQ: see handout – complete and bring to Mrs. B to check1. What is the best wavelength to dial into a colorimeter to

measure absorbance?2. If I measured an absorbance of .45, what is the

concentration?Handouts: NaExtra Credit Opportunity: May 20 6:30 (set up) 7-9 program. Opportunity for Honors Chem parents to see to STEM projects and for everyone to see Believe in Ohio projects

Choosing the appropriate color/wavelength when using a colorimeter

Students should choose the wavelength of light that corresponds to the wavelength of visible light that absorbs the maximum number of photons for a particular solution.

This wavelength can be estimated by choosing a wavelength of light that represents a color that is opposite

in color from the solution color. See Diagram: Red

Orange Violet

Yellow Blue Green
