(75.00) of substance (X) was sintered with (T) (0.065 mol/L) using photometric sintering. The end point of the reaction was determined photometrically. Using the information obtained below, calculate the concentration of the substance (X), then explain the optical properties of each of the reactants, products, and substances leaving the burette.
