Studies on the spectrophotometry of chromium stearate and chromium palmitate in benzene, toluene, xylene, carbon tetrachloride and pyridine solvents provide evidence for the existence of complex ion formation. It has been found that this property can be applied successfully for the estimation of chromium in the concn range 1 to 11 mM/liter at 425 and 580 mƁ. The method can be employed for the higher concn (> 11 m M/liter) range also but the Beer‐Lambert舗s law is applicable only at 425 mƁ.
