The
reaction of cobalt(II) nitrate and potassium thiocyanate produces a
coloured complex, [Co(SCN)4]2-(aq). The initial concentrations of
the reactants after mixing (before any reaction) were 0.250 mol/L
Co(NO3)2(aq) and 0.500 mol/L KSCN (aq). After 20 minutes, the
absorbance of the solution was 0.825. The complex, [Co(SCN)4]2-, is
the only absorbing species (ε b = 9.29 (mol/L)-1). Determine the
concentration of Co2+ at equilibrium.
