When solutions of lead (IL) nitrate and potassium iodide are mixed together, which of the following observations will be true?

Correct option is D

The correct answer is (d) A yellow precipitate of lead iodide will be formed.

• A yellowish solid precipitates when a solution of potassium iodide is added to a solution of lead nitrate that has been taken in a test tube.
• 2KI (aq.) + Pb(NO₃)₂ (aq.) → 2KNO₃ (aq.) + PbI₂(s).
• Lead iodide is this opalescent solid.
• Leadiodide and potassium nitrate are created together.
  

Information Booster:

• When the reactant ions shift around to produce new products, chemical processes known as double displacement reactions take place.
• A double displacement procedure frequently results in the formation of precipitates.
  
• Other names for a double displacement process include double replacement, salt metathesis, and double decomposition.
