Question

What is observed when a solution of potassium iodide solution is added to a solution of lead nitrate? Name the type of reaction. Write a balanced chemical equation to represent the above chemical reaction.

Answer 1

Answer:

• When a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube, precipitate of a yellowish solid is observed. This is Lead Iodide.

• This is a double displacement reaction or a precipitation reaction.

• 2KI + Pb(NO3)² -------> 2KNO³ + PbI²

Potassium Iodide + Lead Nitrate ------>

Potassium Nitrate + Lead Iodide

Answer 2

When potassium iodide is introduced to a solution of lead nitrate in a test tube, the result is a yellowish ppt. This occurs as a result of the creation of Lead Iodide.$(PbI_{2})$. This is an example double displacement reaction. The Balanced chemical reaction is

$2KI(aq) + Pb(NO_{3})_{2} \rightarrow 2KNO_{3}+PbI_{2}$
