English: This is a sample of very pure boron tribromide. The 100% pure chemical is colorless, this sample has better than 99.9% purity, but even a tiny amount of bromine in it gives a clearly visible red/brown color.
Nederlands: Dit is een sample zeer zuiver boortribromide. De 100% zuivere stof is kleurloos, maar in die vorm is het zeer moeilijk te maken. Dit sample is beter dan 99,9%, maar met ca. 0,1% broom in het sample is het toch duidelijk bruin/rood gekleurd.
Čeština: Vzorek velmi čistého bromidu boritého. 100% čistý je bezbarvý, čistota tohoto vzorku je více než 99,9 %. Barvu mu dávají stopy bromu.
