* Bromine is more reactive than iodine: Bromine is higher on the halogen reactivity series, meaning it is more likely to displace iodine from its compound.
* The reaction:
Br₂ (l) + SrI₂ (aq) → SrBr₂ (aq) + I₂ (s)
Explanation:
* Bromine (Br₂) reacts with strontium iodide (SrI₂), which is dissolved in water.
* The more reactive bromine atoms displace the iodine ions (I⁻) from the strontium iodide.
* This forms strontium bromide (SrBr₂), which remains dissolved in the water, and elemental iodine (I₂), which precipitates out of solution as a solid.
Key features of a single displacement reaction:
* One element replaces another element in a compound.
* The reactants are an element and a compound.
* The products are a new element and a new compound.
