Welcome back to our science experiment series! In today's video, we are diving into Chapter 1: Chemical Reactions and Equations to perform and explain Activity 1.2 from the Class 10 NCERT Science textbook.
​In this experiment, we explore one of the most visually striking chemical reactions: the reaction between Lead Nitrate and Potassium Iodide. This activity is a perfect example of a Double Displacement Reaction and a Precipitation Reaction.
​🧪 Experiment Overview:
​The goal of this activity is to observe what happens when two colorless solutions are mixed and to identify the indicators of a chemical reaction.
​What You Will See in This Video:
​Preparation: We take a clear solution of Lead Nitrate in a test tube.
​The Reaction: We slowly add a clear solution of Potassium Iodide to it.
​The Observation: Watch as a brilliant yellow precipitate instantly forms! This "Golden Rain" effect is a hallmark of this specific chemical reaction.
​The Science Behind It:
​When these two compounds react, they exchange their ions to form two new substances:
​Lead Iodide (PbI_2): This is the yellow solid (precipitate) that you see. Because it is insoluble in water, it settles at the bottom of the test tube.
​Potassium Nitrate (KNO_3): This remains dissolved in the solution and is colorless.

Key Takeaways:
​Precipitation Reaction: A reaction that produces an insoluble solid (precipitate).
​Double Displacement: A reaction where there is an exchange of ions between the reactants.
​Indicator of Reaction: In this case, the change in color and the formation of a precipitate confirm that a chemical reaction has taken place.
​Check Your Knowledge:
​Based on the textbook, try to answer these:
​What was the color of the precipitate formed?
​Can you name the compound that precipitated?
​Why is this called a double displacement reaction?
