Bromoform is an organic, colorless liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to chloroform. It can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminum bromide.
