DANGEROUSLY Reactive
Short answer: Aluminum reacts vigorously with liquid bromine, often after a short delay while the metal's oxide layer is breached. The highly exothermic reaction produces sparks, flames and fumes of aluminum bromide.
Aluminum gives up electrons and bromine accepts them. The footage shows aluminum foil reacting in a dish of bromine.
What should you know about DANGEROUSLY Reactive?
Quick facts. Each one stands alone and has a stable ID you can cite.
The reaction releases heat.
It makes aluminum bromide.
Video transcript: DANGEROUSLY Reactive: Aluminum Dropped in Liquid Bromine Bursts Into Flame
Did you know? The reaction between liquid bromine and solid aluminum is highly exothermic and produces intense heat and bright flames. When aluminum comes into contact with bromine, it quickly oxidizes, breaking apart the bromine molecules. The reaction releases aluminum bromide as a product, which forms a white smoke. This interaction can be dangerously reactive, as bromine is a volatile, corrosive liquid that readily accepts electrons, while aluminum is a highly reactive metal with a strong tendency to donate electrons. NOW YOU KNOW!
