Solution K-1 contained NiSO4 because when solution K-9‚ ammonia which was identified by its pungent odor‚ was added‚ an inky dark blue color was made. Iron (Fe (NO3)3) was determined to be in test tube K-2. KSCN was found in test tube K-11 since Fe (NO3)3 and KSCN makes a bloody color when mixed together. Flame tests were conducted in which K-8 burned green which identifies Cu(NO3)2‚ and the

Our informal interpretation is protection should not be required within the pockets. Normally‚ the total volume of unprotected ceiling pockets is 1‚000 cu ft.

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.
