Question
Classify which type of reaction the golden rain reaction is.
Solution
The golden rain reaction is an example of a double displacement reaction, also known as a metathesis reaction.
Here are the steps to classify it:
-
Identify the reactants and products: In the golden rain experiment, lead (II) iodide is dissolved in hot water and potassium iodide is added. The reaction produces potassium nitrate and lead (II) iodide.
-
Look at how the ions exchange: In the reaction, the lead (II) ion from lead (II) iodide exchanges with the potassium ion from potassium iodide to form lead (II) iodide and potassium nitrate.
-
Identify the type of reaction: Since the ions in the reactants are exchanging to form new products, this is a double displacement reaction.
So, the golden rain reaction is a double displacement reaction.
