Question

What happens when potassium iodide is mixed to lead acetate? Tell the chemical formula too

Answer 1

Answer:

1. Lead (II) ions and iodide ions can be combined to form a beautiful bright yellow precipitate.

2. This is one of the more spectacular precipitation reactions.

3. When a colorless solution of potassium iodide and a colorless solution of lead acetate or lead nitrate are added to each other, then a beautiful precipitate is formed.

4. The chemical formula for it is:-

$Pb (CH_{3} COO)_{2} + 2 KI = PbI^{2} + 2 K (CH3COO) PbI^{2}$ is a yellow precipitate.

Answer 2

Answer:

Potassium iodide on reacting with leas acetate gives lead iodide and potassium acetate.

Explanation:

On mixing potassium iodide with lead acetate, lead acetate dissolves in water to give lead ion and acetate ion. This on reacting with potassium iodide the lead ion joins with iodide ion to form lead iodide and potassium ion joins with acetate ion to form potassium acetate. Thus potassium iodide on reacting with leas acetate gives lead iodide and potassium acetate.

                                     2KI + Pb(C₂H₃O₂)₂ →  K(C₂H₃O₂) + PbI₂
