We then confirmed that are blank cuvettes read 0 on the Genesys spectrophotometer . We then measured the 0.500 M Cu2+ absorbance of wave length every 25 nm until reaching 950 nm. We then found our wavelength at which A is a maximum and repeated measuring every 5 nm.
We then diluted our solution further using a pipette adding 20 ml, 10 ml, and 5 ml to three separate 25 ml volumetric flask and diluted to the calibration line and swirled vigorously... displayed next 300 characters
