YELLOW PRECIPITATES OF LEAD (II) IODIDE | PRECIPITATION REACTION CHEMISTRY

Chemical Reaction Demonstration
🧪 The demonstration involves adding a few drops of potassium iodide ($\text{KI}$) solution using a dropper into a test tube containing lead nitrate ($\text{Pb}(\text{NO}_3)_2$) solution.
🟡 The immediate observation is the formation of yellow precipitates of lead iodide ($\text{PbI}_2$).
⚛️ This specific reaction is identified as a classic example of a double displacement precipitation reaction.

Key Points & Insights
➡️ The reaction observed is the formation of $\text{PbI}_2$ precipitate when $\text{KI}$ reacts with $\text{Pb}(\text{NO}_3)_2$.
➡️ The chemical process demonstrated is classified as a double displacement precipitation reaction.
