C. 1 – 6: DISCUSSION QUESTIONS1.Your TA will provide you with the correct concentration of the dye in the powdereddrink solution. Calculate the percentage error for your data. % error= 0.40-0.24/0.24 = 66.6766.67%2.The empirical formula for the Brilliant Blue dye is: C37H34N2O9S3Na2and the formulaweight are 792.86g/mol. How would you prepare a 5.25 x 10-6M solution of BrilliantBlue dye. How many grams of the dye you need to add to a 1.00 L of water to makethis solution.% error =(experimental value - accepted value)accepted value× 100
Molarity of dye prepared= 5.25*10-6M= 5.25*10-6mol/L5.25*10-6mol of dye is to be added to 1L of waterMass of dye to be added= mol * formula mass= (5.25*10-6mol) * (792.86 g/mol) = 0.004162 grams3.Many dyes used in food product are classified as hazardous chemicals in their pureform. Why, then, can they be safely used in those food products? When the dyes are presented in its pure form, they are hazardous. Dyes are not harmfulwhen they are present within suggest limits. Therefore, food dyes only have a limited amount which causes them not to be harmful.4.We used 630nm wavelength to carry out the absorbance measurements. What isthe color of light that the powdered drink solution primarily absorbs? The color observed in the experiment is blue, because of the dye being a blue hue.The color shown is the emitted color. On a color wheel color opposite to blue isorange, which means orange is the color absorbed by the solution.
