Recently in this laboratory the refractometric study of 2-chloro-4-amino phenol was studied at various percentage compositions of solvents to investigate the effect of structure of 2-chloro-4-amino phenol in various percentage compositions. The data and results obtained during this study give the effect of ethanol and water in the ethanol-water system. The 0.1M solution of 2-chloro-4-amino phenol in different percentage of ethanol- water at different concentration of 2-chloro-4-amino phenol ( 0.1M ,0.075M ,0.056M ,0.042M ) in 60% ,70% and 80% ethanol- water mixture were prepared .All weighing was made on Mechaniki Zaktady Precyzying Gdansk Balance ( Poland make ( ±0.001gm)). The densities of the solutions were determined by a bicapillary pyknometer ( ± 0.2% ) having a bulb volume of about 10 cm 3 and capillary having an internal diameter of 1 mm . The refractive indices of solvent mixture and solutions were measured by Abbe's refractometer (± 0.001). The temperature of prism box was maintained at 29 0 C. Initially, the refractometer was calibrated with glass piece (n = 1.5220) provided with the instrument. II. Observation and calculation
