Question

Which of the following is FALSE regarding the absorption and emission of light by solutions of colored compounds?

• A. The color of the solution is the color of light that will be most strongly absorbed.
• B. Solution colors are the result of electron transitions between excited states and the ground state.
• C. A plot of absorbance vs concentration will be a straight line.
• D. The color of the solution is due to light that it transmits, rather than light that is absorbs.

Answer 1

Answer: (D)

The color of the solution is due to light that it transmits, rather than light that is absorbs.

i) Color of colloidal solution depends upon particle size and also on direction in which it is being viewed.
ii) The color of solution is the color of light that will be most strongly absorbed.
Thus option D is false
