Question
Write the ionic equation for the displacement reaction between chlorine and potassium bromide.
Answer
Cl2 + 2KBr → 2KCl + Br2
Explanation
This question tests the ability to write an ionic equation for a halogen displacement reaction. The answer shows the reactants and products clearly, demonstrating understanding of how chlorine displaces bromine in the reaction.
Common mistake
Common Mistake in Writing Ionic Equations
Students often forget to balance the charges in ionic equations for halogen displacement reactions.
To write a correct ionic equation, ensure that the total charge on both sides is equal. For example, when writing the equation for the displacement of bromine by chlorine, start with Cl2 + 2Br- → 2Cl- + Br2. Check that the charges balance: 0 on the left and -2 on the right, which is incorrect. Adjust to ensure both sides have the same total charge.
