Fundamentally, because this reaction reduces the Gibbs free energy of the reactants when they are converted to products. Chlorine atoms have substantially greater electronegativity than bromine atoms, while chloride and bromide ions both have about the same, very low, electronegativity. Therefore, chemical potential energy is reduced by removing an electron from each bromide ion to form a bromine atom and transferring the electron so removed to chlorine atoms to form chloride ions instead of bromide ions.
Chlorine is more reactive than bromine and has a higher tendency to gain electrons compared to bromine. When chlorine is added to potassium bromide solution, chlorine ions displace bromine ions from the solution by forming more stable chlorine compounds with potassium ions. This displacement reaction occurs due to the difference in reactivity and electron affinity between chlorine and bromine.

Will chlorine and potassium bromide react?
Yes, chlorine will react with potassium bromide to form potassium chloride and bromine. This is a displacement reaction where the more reactive chlorine displaces bromine from potassium bromide.
What is the name of the reaction of potassium bromide with chlorine?
The reaction of potassium bromide with chlorine is known as a displacement reaction, where the more reactive chlorine displaces the less reactive bromide to form potassium chloride and elemental bromine.
Why does the color of aqueous potassium bromide change when chlorine gas is bubbled into it?
When chlorine gas is bubbled into aqueous potassium bromide, a redox reaction occurs where chlorine oxidizes bromide ions to bromine atoms. The resulting bromine atoms form a reddish-brown solution, giving the potassium bromide solution a color change.
What is the Reaction between fluorine and potassium bromide?
When fluorine reacts with potassium bromide, the fluorine displaces bromine from the compound to form potassium fluoride and bromine gas. This is a redox reaction where fluorine is reduced and bromine is oxidized.
What reaction happens between aqueous chlorine and sodium bromide solution?
The reaction between aqueous chlorine and sodium bromide solution results in the displacement of bromine by chlorine, forming sodium chloride and bromine gas as products. This is a redox reaction where chlorine is reduced and bromine is oxidized.
Will chlorine and potassium bromide react?
Yes, chlorine will react with potassium bromide to form potassium chloride and bromine. This is a displacement reaction where the more reactive chlorine displaces bromine from potassium bromide.
Why chlorine displaces bromine from potassium bromide?
Chlorine is a stronger oxidizing agent than bromine.
What happens when a solution of chlorine is mixed separately with potassium bromine solution and potassium iodide?
When chlorine is mixed with potassium bromide solution, chlorine will displace bromine to form potassium chloride. Similarly, when chlorine is mixed with potassium iodide solution, chlorine will displace iodine to form potassium chloride. These reactions are examples of displacement reactions where a more reactive element displaces a less reactive element from its compound.
What is the name of the reaction of potassium bromide with chlorine?
The reaction of potassium bromide with chlorine is known as a displacement reaction, where the more reactive chlorine displaces the less reactive bromide to form potassium chloride and elemental bromine.
What color change occurs when chlorine gas is passed through a solution of potassium bromide?
When chlorine gas is passed through a solution of potassium bromide, the solution will change from colorless to yellow. This indicates the formation of elemental bromine as a result of the reaction between chlorine and bromide ions.
Do chlorine and potassium bromine react?
Chlorine and potassium bromide can react to form potassium chloride and bromine. This reaction typically occurs when chlorine gas is bubbled through a solution of potassium bromide.
Which statement best describes the formula equation Cl2 g 2 KBr aq 2 KCl aq Br2 l?
