* Electronegativity: Chlorine is more electronegative than bromine. This means chlorine has a stronger attraction for electrons.
* Reactivity: Higher electronegativity translates to greater reactivity. Chlorine, being more reactive, will readily pull electrons away from bromine in the potassium bromide compound.
* Reaction: The reaction between chlorine and potassium bromide is a single displacement reaction:
Cl₂ (g) + 2KBr (aq) → 2KCl (aq) + Br₂ (l)
* Chlorine (Cl₂) reacts with potassium bromide (KBr).
* Chlorine takes the place of bromine in the compound, forming potassium chloride (KCl).
* Bromine (Br₂) is released as a liquid.
In essence, chlorine's stronger pull on electrons allows it to "kick out" bromine from the compound, forming a new compound with potassium. This reaction is driven by the tendency of elements to achieve a more stable electron configuration.
