The present research paper discusses the absorbance measurement by using different mixtures of solutions filter. The expected and observed transmittance spectra were recorded and the results have been compared with the wavelength of maximum absorbance, maximum percentage of transmittance values. Mixture of copper nitrate, Copper chloride, Sodium dichromate, Potassium permanganate and Rhodomine- B were used in the present study. Cucl2+Na2Cr2O7 mixture solutions desirable results among other mixtures of solution filters. It is commonly know that every compound absorbs or transmits light over a firm range of wavelength. Colorimetry is one of the most useful devices of quantitative investigation in several areas such as chemical science, physical science, life science, and Medical science applications.
