Detailed Solution

Concept- In double displacement reaction, the two ionic compounds react and their ions interchange to form a new set of ionic compounds.
If during a double displacement reaction, a solid product is formed, it is also called precipitation reaction.
When a solution containing potassium iodide is mixed with a solution containing lead nitrate in a test tube, a precipitate of a yellowish solid is observed.
The yellowish solid formed is lead iodide. Another product is potassium nitrate. The chemical reaction for this is;
Question ImageThus, this is a double displacement reaction and also a precipitation reaction.
Hence, the correct option is 1.
