Determining the Concentration of a Solution: Beer's Law

CALCULATIONS/SET-UPS

Initial concentration of Fe^3+ = (Beakers 1 through 4)	[Fe3+]i = X (0.00200 M)
Initial concentration of SCN^- = (Beakers 1 through 4)	[SCN-]i = X (0.00200 M)
Concentration of FeSCN2+in the standard solution = (Beaker 5)
Equilibrium concentration of FeSCN2+ = (Beakers 1 through 4)	[FeSCN2+]eq = X [FeSCN2+]std
Equilibrium concentration of Fe3+ = (Beakers 1 through 4)	[Fe3+]eq = [Fe3+]i – [FeSCN2+]eq
Equilibrium concentration of SCN- = (Beakers 1 through 4)	[SCN-]eq = [SCN-]i – [FeSCN2+]eq
Equilibrium constant, Kc = (Beakers 1 through 4)	Kc =
Range of Kc values =	Largest Kc value – smallest Kc value
Average of Kc values =	(Kc1 + Kc2 + Kc3 + Kc4) / 4
