Question

iron(iii) thiocyanate spectroscopywavelength of maximum absorbancethe student prepares to create thecalibration curve for the red fescn²⁺solution.consider the color wheel and wavelengthranges to answer the question.which wavelength should the studentuse to create the calibration curve?ultraviolet: 300-400 nmred: 640-700 nmgreen: 480-560 nmviolet: 400-450 nm

Explanation:

Spectroscopy uses the complementary color of the solution's visible color for maximum absorbance. The red [FeSCN]²⁺ solution has a complementary color of green, which corresponds to the 480-560 nm wavelength range.

Answer:

green: 480-560 nm
