Concept explainers
(a)
Interpretation:
Whether the dichromate ion is colored or not is to be stated on the basis of general principles.
Concept introduction:
An object absorbs
(b)
Interpretation:
Whether the peroxide ion is colored or not is to be stated on the basis of general principles.
Concept introduction:
An object absorbs light of some wavelength and reflects back some light with the complementary wavelength. When the wavelength of that reflected light is in the visible region of the electromagnetic spectrum, then the human eyes can see the color of that object. The wavelength of visible light lies in the range of
