Question

Prepare a graph of absorbances for solutions B, C, D, E, F against the Kool said in ppm on a mass to volume basis. Y axis should be experimental absorbances and the x axis should be ppm. Determine concentrations of dye in the other solution a b c d e f in terms of dye in C.

Part I Mass of beaker: oa.ass Mass of beaker + Kool Aid: O 3 : 443g Kool Aid type: chen Attach the print out of the spectrum to your POSTLAB form. Part II. Variation of absorbance with concentration ratio of [ dye] to 1.0 0.25 0.175 0.10 0.063 0.025 absorbance not measured O.589 solution soaodye] in solution A O.LuS

Answer 1

From table: [dye in B]/ [dye in A] = 0.25, [dye in F]/ [dye in A] = 0.175 [dye in C]/ [dye in A] = 0.1, [dye in D]/ [dye in A] = 0.063, [dye in E]/ [dye in] = 0.025. From 2 (c), [dye in C] = 5.56 mg/L. [dye in B]/ [dye in C] = [dye in B]/ [dye in A]/ [dye in C]/ [dye in A] = 0.25/0.1 = 2.5 [dye in B] = 2.5 times 5.56 = 13.9 mg/Lit Similarly, [dye in F] = 1.75 times 5.56 = 9.73 mg/Lit [dye in D] = 0.63 times 5.56 = 3.5028 mg/Lit [dye in E] = 0.25 times 5.56 = 1.39 mg/L
