Lead nitrate = Pb[NO]₂ Potassium Iodide = KI
1. Colour of the precipitate formed is Yellow
2. KI + Pb[NO₃]₂ -----> KNO₃ + PbI₂ [Skeletal form of equation]
3. 2Kl+ Pb[NO₃]₂ -----> 2KNO₃ + PbI₂ [ Balanced equation]
4. Yes this is a double displacement reaction.
Also, as yellow precipitate is formed , this is also an example of precipitation reaction.

Answer:
(i) The colour of the precipitate is yellow. The name of compound formed as a precipitate is Pbl2 (lead iodide).
(ii)KI + Pb[NO₃]₂ -----> KNO₃ + PbI₂
-----> UNBALANCED EQUATION
2Kl+ Pb[NO₃]₂ -----> 2KNO₃ + PbI₂
----> BALANCED EQUATION.
This is an example of double displacement reaction.
iii) Yes, it is also a double displacement reaction(or precipitation reaction).
I hope you satisfied with my answers,so plz mark it as brainlist.....☺️☺️....
