Question

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

A.

A white precipitate of lead iodide will be formed.

B.

No reaction will occur.

C.

A white precipitate of potassium nitrate will be formed.

D.

A yellow precipitate of lead iodide will be formed.

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.
