![Activity 1.2 lead nitrate with potassium iodide](https://studdy.in/wp-content/uploads/2019/02/830px-Lead_II_iodide_precipitating_out_of_solution-262x300.jpg)
Brief procedure: Activity 1.2 asks us to mix an aqueous solution of lead nitrate with potassium iodide to check what happens.
Observation: A yellow colour precipitate appears at the bottom.
Explanation: Lead nitrate and potassium iodide; both are colourless. They react with each other to form a yellow precipitate of lead iodide. Lead iodide settles down at the bottom of the tube.
Pb(NO3)2(aq)+ 2KI(aq) → PbI2(s) + 2KNO3(aq)
Next: Reaction of zinc with dilute acid. Activity 1.3.
