Q84P - Chemistry: Molecular Nature Of Matter And Change

Question

In terms of the theory of color absorption, explain two ways that a solution can be blue.

Step-by-Step Solution

Answer

If the object absorbs all of the wavelengths except blue, it will reflect or transmit blue light

 

If the object absorbs only orange wavelengths, which are complementary to blue wavelengths, the remaining wavelengths will be reflected as blue

Step 1: Given data

A solution is blue.

Step 2: Color absorption theory will be used

Every color has its complementary color: Red - Green Yellow - Violet Orange - Blue; There are two ways in which an object can have some particular color.

Step 3: Two ways that the solution can be blue

If the object absorbs all of the wavelengths except blue, it will reflect or transmit blue light.

If the object absorbs only orange wavelengths, which are complementary to blue wavelengths, the remaining wavelengths will be reflected as blue.
