Q4. A polluted water sample contains approximately 0.1 ppm of chromium, [M=52 g mol-1]. The determination for Cr(VI) based upon absorption by its diphenylcarbazide complex Amax= 540nm E= 41 700 Lmol-1 cm-1_was selected for measuring the presence of the metal. What optimum path length of cell would be required for a recorded absorbance of the order of 0.4?
