Question

The reaction of lead acetate solution with dilute hydrochloric acid to form lead chloride and an acetic acid solution is a:
A. Displacement reaction
B. Precipitation reaction
C. Decomposition reaction
D. Neutralization reaction

Answer 1

Hint: Lead acetate is also known as lead (II) acetate, is a white crystalline chemical compound with the formula \[Pb{({C_2}{H_3}{O_2})_2}\]. The displacement reaction is the one in which the atom or set of atoms is displaced by another atom in a molecule. Therefore, a more reactive metal displaces a less reactive metal.

Complete step by step answer:
Lead acetate was first produced in the United States in 1994. Lead belongs to the group 4 elements. Now, lead acetate reacts with dilute hydrochloric acid to form lead chloride and acetic acid.
The reaction is as shown:
 $Pb{(C{H_3}COO)_2} + 2HCl \to PbC{l_2} + 2C{H_3}COOH$
Now, this reaction is known as double displacement reaction as both the reactants exchange ions to form new products. Moreover, in this reaction the positive and negative ions of two ionic compounds exchange places to form two new compounds.
Further, lead acetate also reacts with hydrogen sulfide and forms lead sulfide and acetic acid. The chemical equation is as shown:
 $Pb{({C_2}{H_3}{O_2})_2} + {H_2}S \to PbS + 2H{C_2}{H_3}{O_2}$

Hence, option A is correct.

Note:
Lead acetate is used in silk printing and dyeing as a mordant, as a dryer in paints and varnishes, and in the preparation of other lead compounds. It is also used as a secret ingredient to sweeten wine and preserve food. However, it is not used as a sweetener anymore because it may cause serious health problems such as stomach pain, diarrhea, cancer, and elevated blood and urine rates and in most extreme cases it may even cause death.
