an aqueous solution of cobalt and nickel ions was examined by multicomponent analysis using a 1.00 cm cell and two different wavelengths (denoted by subscripts 1 and 2) selected based on the absorption spectra of the two ions when complexed with a highly colored complexing agents. absorption data were as follows:
molar absorptivity: Co1= 2.775
molar absorptivity: Co2= 1.001
molar absorptivity Ni1= 1.057
molar absorptivity Ni2= 1.753
Absorbance: AT1= 0.264
absorbance: AT2= 0.143
what are the molar concentration of cobalt and nickel in this solution?
