Answer:
No, Fe^3+will not interfere
Explanation:
Whether of not the two ions will interfere will depend on the region of the visible spectrum where they absorb.
Now Fe^3+ at a wavelength of 600nm for the determination of Cu^2+ ion will not interfere. This is because, Fe^3+ absorbs in the blue (450-480 nm) region while Cu+2 absorbs in the yellow (560-600 nm) region then appears blue in color.
