Chemical ThinkingP2 S2Preparatory Work v1.5 | 1Project 2 Session2Preparatory WorkYour TA’s name: Dylan DyerYour name: Liza IsayevLab section: 3iYour email: [email protected]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 in your P2 S1 Preparatory Work, you should know the dye(s) present. You cannot use the isolateddye(s) directly to find ε, for the concentration is unknown – in fact, you will eventually seek this concentration. However, you will have thepreviously mentioned stock solutions of pure dye for which the concentration is known (seven stock dye solutions, one for each of the sevenFD&C dyes). Thus, to find the absorbance-concentration relationship, the stock dye solution(s) must be used. Incorporating the appropriatestock dye solution(s) design an experimental plan to find the molar absorptivity (ε
