Quick student answer
Which of the following halogens can displace iodine from potassium iodide solution?
Direct answer
All of the above halogens can displace iodine from potassium iodide solution.
Key terms
- Displacement Reaction: A chemical reaction where one element replaces another in a compound.
- Ionic Equation: An equation that shows the ions involved in a chemical reaction, omitting the spectator ions.
Common trap
Incorrectly balancing ionic equations: Ensure that both the number of atoms and the total charge are balanced on both sides of the equation.
