What is the color of bromine liquid?

• A. Red-Brown
• B. Orange
• C. Green
• D. Pale Yellow

Answer: (A)

Color comes from which wavelengths of visible light a substance absorbs. Bromine, a halogen that is liquid at room temperature, absorbs blue light strongly. The light that isn’t absorbed is enriched in the red-brown end of the spectrum, so the liquid looks reddish-brown. This distinctive hue sets bromine apart from other halogens in different states (for example, chlorine is greenish-yellow and iodine is violet-black), and the overall effect is a red-brown liquid color.
