Beer 's law says that the absorbance at a given wavelength is directly proportional to the molar concentration of the substance that absorbs light . As a linear equation , Absorbance slope of the curve molar concentration y-intercept . A straight line is generally obtained when the concentrations are plotted against the absorbance levels . The blank test is done to standardize or calibrate the spectrophotometer . It contains a sample cell fitted with a portion of the pure solvent . It is the same solvent...

The vertical axis had absorbance scaled from 0 to 0 .35 and the horizontal axis had time scaled from 0 to 20 minutes . Calibration of the Colorimeter for 0 transmittance (no light ) and 100 transmittance (maximum light : 5 . The outside of the cuvette was cleaned and dried using a chemwipe and the cuvette was filled 3 /4th with distilled water in a manner to avoid bubbles in the solution . The cuvette was placed in the colorimer 's cuvette slot with...
