8. Colored complex of concentration 0.001 mol/l with optical density 0.65
with a layer thickness of 10 mm, extracted with amyl acetate, distribution coefficient
which relative to the acidified aqueous solution K=99. What will the optical
the density of the aqueous solution after a single extraction with amyl alcohol (VSP: VB = 1:10) and the optical density of the extract after diluting it 10 times, if the molar absorption coefficient does not change?
