Question : In the double displacement reaction of aqueous potassium iodide and aqueous lead nitrate, a yellow precipitate of lead iodide jd formed. While performing the activity, if lead nitrate is not available, which of the following can be used in place of lead nitrate?

$~$

• Lead sulphate (insoluble)

• Lead acetate

• Ammonium nitrate

• Potassium sulphate

$\:$

$\qquad$____________

$\:$

Answer : Lead acetate

$\:$

${\bf \red{2KI(aq)~+~Pb(NO_3)_2~\rightarrow~PbI_2(s)~+~2KNO_3}}$

$\:$

Explaination :

• Lead sulphate is insoluble in the solution.

• Ammonium nitrate and potassium sulphate have different ions.

• Lead acetate dissolves in water to give lead ion and acetate ion.

• On reacting with potassium iodide, the lead ion joins with the iodine ion to form lead iodide and potassium ion joins with acetate ion to form potassium acetate.

• Henceforth, lead acetate is the one that can be used in the place of lead nitrate.
