my actual findings. Our lab consisted of three parts: determining the proper wavelength for the spectrophotometer‚ constructing a calibration curve for Cu(NH3)42+‚ and finally determining the actual content of copper in a penny. IN the first step of the lab‚ we used water to calibrate our spectrophotometer‚ and then measured the absorbance of Cu(NH3)42+ at different wavelengths‚ in order to determine the optimal one. In our group‚ we determined 600nm was the optimat wavelength with an absorption

Uniformity Coefficients of less than 4 usually indicate uniform soils while well graded soils have uniformity coefficients equal to or greater than 4. Cu > 5 is an indication of gravels and Cu > 6 is for sands. © Coefficient of Gradation or Coefficient of Curvature Cg: This is a measure of the shape of the particle size curve. Cg = (D30)2/ D60 x D10 4.6 Cg from 1 to 3 ------- connotes a well graded soil 4

CHAPTER 3 Studies on Mn (II)‚ Co (II)‚ Ni(II)‚Cu(II)‚Zn(II) and Cd(II) Complexes of Dimedone bis Semicarbazone (H2DSC) During the past few decades‚ major developments have been achieved in the research of coordination compounds with special emphasis on metal complexes of Schiff bases containing nitrogen and oxygen donors 1-5 . This may be due to their stability‚ biological activity5-6and potential applications in many fields 9-10. Biological activity of complexes derived from semicarbazide has
