Answer:
Step-by-step explanation:
To analyze Cu2+ ions in aqueous solution, a suitable wavelength would be in the visible range of the electromagnetic spectrum. Copper ions are known to exhibit absorption in the visible region due to their electronic transitions.
The electronic transitions in transition metal ions, such as Cu2+, typically involve the movement of electrons between d orbitals. For copper ions, the most common transition involves the movement of an electron from the 3d orbital to the 4s orbital. This transition results in the absorption of light in the blue-green region of the visible spectrum.
The wavelength of light that corresponds to the blue-green region is around 500-550 nanometers (nm). So, a suitable wavelength to analyze Cu2+ ions in aqueous solution would be around 500-550 nm.
It is important to note that the exact wavelength for analyzing Cu2+ ions may vary depending on the specific experimental conditions, such as the concentration of the ions and the presence of other substances in the solution. Therefore, it is always recommended to consult scientific literature or follow established analytical methods for precise wavelength selection when conducting experiments involving Cu2+ ions analysis.
In conclusion, a suitable wavelength to analyze Cu2+ ions in aqueous solution would be around 500-550 nm, corresponding to the blue-green region of the visible spectrum.
