Caution: This activity needs the teacher’s assistance.

Activity - Take lead nitrate solution in a test tube. Add potassium iodide solution to this. What do you observe?

Observation- On mixing two solutions a yellow colour precipitate of lead iodide is formed.

Pb (NO3)2 (aq)    + 2KI (aq) → PbI2 (s)  + 2KNO3 (s)

          

Conclusion: On mixing  Pb(NO3)2 and KI, the yellow-coloured precipitate of PbI2 is obtained.
