Write an initial experimental plan to determine the molar absorptivity (ε) of the FD&C food dye(s)present in your assigned commercial candy. From the identification experiment planned above, you willknow the dye(s) present. You cannot use the isolated dye(s) directly to find ε, for the concentration isunknown – in fact, you will eventually seek this concentration. However, you will have the previouslymentioned stock solutions of pure dye for which the concentration is known (seven stock dye solutions,one for each of the seven FD&C dyes). Thus, to find the absorbance-concentration relationship, the stockdye solution(s) must be used. Incorporating the appropriate stock dye solution(s) design an experimentalplan to find the molar absorptivity (ε) of the FD&C food dye(s) present in your assigned commercialcandy. Beer-Lambert law:A = εbcA: Absorbabilityε: Molar absorbability.b: Length of the cuvette.c: Molar concentration of the sample.Table 1.
