Question
Classify which type of reaction the golden rain reaction is.
- Composition
- Decomposition
- Single displacement
- Double displacement
Solution
The golden rain reaction is a type of double displacement reaction.
Here's a step-by-step explanation:
-
In the golden rain experiment, lead(II) iodide is dissolved in hot water and potassium iodide is added.
-
The lead(II) ions and iodide ions from the potassium iodide swap, or displace each other.
-
This results in the formation of potassium nitrate and lead(II) iodide.
-
The lead(II) iodide then precipitates out of the solution, creating the "golden rain".
So, because the ions in the reactants are swapping places, this is a double displacement reaction.
