### Transcription for Educational Website #### 1. Beer’s Law Expression Factors What factors are included in the Beer’s law expression for determining how much light passes through a liquid solution? #### 2. Impact of Fingerprints on Test Results How would your test results be affected if you left fingerprints on the sides of the cuvette in line with the light path of the spectrometer (or colorimeter)? #### 3. Absorption of Sunset Yellow The chemical sunset yellow, also known as yellow #6, looks yellow. What color(s) must be absorbed by this chemical? #### Diagram: RGB System - The diagram is a Venn-like representation of the RGB (Red, Green, Blue) system for transmitted light. - It illustrates the additive color system using colored lights. - The overlaps between the circles indicate color combinations: - Overlapping Red and Green produce Yellow. - Overlapping Green and Blue-Violet produce Cyan. - Overlapping Red and Blue-Violet produce Magenta. - The intersection of all three primary colors generates White. #### 4. Calculation of Concentration Sunset yellow has an extinction coefficient of 20,000 M⁻¹ cm⁻¹ at a lambda max of 470 nm. What is the concentration of a solution that has an absorbance of 0.893?
