Group 7 Displacement: Ionic Equations | GCSE Chemistry
A more reactive halogen can displace a less reactive halogen from an aqueous solution of its salt.
Write the ionic equation for chlorine displacing bromine ($Cl_2 + 2Br^-$).
What is Group 7 Displacement: Ionic Equations | GCSE Chemistry?
"A reaction where a more reactive halogen replaces a less reactive one in a compound, often explained using ionic equations."
Mendeleev left gaps in his periodic table. Why?
Why did Mendeleev's periodic table become widely accepted?
Which halogen is a red-brown liquid at room temperature?
How many electrons do Group 1 metals have in their outer shell?
Halogen Displacement
Chlorine can displace Bromine and Iodine.
Bromine can displace Iodine but NOT Chlorine.
Ionic equation: $Cl_2 + 2Br^- ightarrow 2Cl^- + Br_2$.
The halogen that is displaced causes a color change in the solution.
Redox Tip: The more reactive halogen is REDUCED (gains electrons), while the halide ion is OXIDISED (loses electrons).
