Question

Write the observation when solution of potassium iodide and lead nitrate are mixed together

Answer 1

Answer: yellow precipitate of potassium nitrate KNO3 is formed

Explanation:

Double displacement reaction

Answer 2

Answer:

Potassium Nitrate

EXPLAINATION:

Lead nitrate = Pb[NO]₂

Potassium Iodide = KI

When Lead Nitrate and Potassium Iodide are mixed we get Potassium Nitrate and an insoluble solid [ precipitate ] lead iodide.

Colour of the precipitate formed is Yellow [ Lead Iodide ]

KI + Pb[NO₃]₂ -----> KNO₃ + PbI₂

-----> UNBALANCED EQUATION

2Kl+ Pb[NO₃]₂ -----> 2KNO₃ + PbI₂

----> BALANCED EQUATION

This is an example of double displacement reaction.

Also , as yellow precipitate is formed , this is also an example of precipitation reaction.
