In , the
ion absorbs visible light in the blue-violet range, and the compound is yellow-orange. In
, the
ion absorbs visible light in the red range, and the compound is blue-gray. Explain these differences in light absorbed and color of the compound.
Short Answer
The color absorbed by the compound in coordinate compounds is opposite of the color that is emitted by it. The complementary pairs of colors that are available is based on color wheel. The compounds absorbing visible light in the range of blue-violet rays, emit the color in the range of yellow-orange. On the other hand, the complexes that absorb the visible light in the range of red color emit blue or green light.
Step by step solution
Given information
In the coordinate compound , the ion
when absorbs the visible in the range of blue-violet, the compound shows the color in the range of yellow-orange. But when the coordinate compound
has the ion
getting absorbed the visible light in the range of red color, the compound shows the color as blue-gray.
The color wheel for complementary pairs of colors
The complementary pairs of colors are given by thecolor wheel as:
The complementary pairs of colors wheel for the coordinate compound
Based on the color wheel, the complementary pairs are decided. The compounds absorbing visible light in the range of blue-violet emits color in the range of yellow-orange, whereas those absorbing red range emit the light of either blue or green color.
