Question

Find the total number of colored species out of the following: Cl₂, NO₂, NH₃, AgNO₂, CrO₂Cl₂, N₂O₄, Cu₂[Fe(CN)₆]

TestHub · Accepted Answer

Color depends on the absorption of visible light by the species.

Cl₂ (greenish yellow), NO₂ (brown), AgNO₂ (yellow), and Cu₂[Fe(CN)₆] (reddish brown) are colored species.

NH₃, CrO₂Cl₂, and N₂O₄ are colorless.

Therefore, the total number of colored species = 4.
