Problem- Part 1- Which will have a greater absorbance as measured by a spectrometer: weak ice tea or strong ice tea? Which will have a greater transmittance?
Part 2- Why do we usually use the wavelength of maximum absorbance( max) to make quantitative measurement of concentration?
Part 3- When a Beer law calibration curve is constructed, what variables are plotted on the x and y axes? what is obtained from the slope of the line generated?
Part 4- What solvent will be used as the reference solvent (or blank) in the spectrometer?
Part 5- What is the purpose of adding ammonium hydroxide to the aqueous solution of copper ions?
