Question

Does a reaction occur when aqueous solutions of lead(II) acetate and zinc bromide are combined? O yes no If a reaction does occur, write the net ionic equation. Use the solubility rules provided in the OWL Preparation Page to determine the solubility of compounds, Use the pull-down boxes to specify states such as (aq) or (8).

Answer 1

Ans :- YES, the reaction takes place and the balance chemical reaction is :

Pb(CH₃COO)₂ (aq) + ZnBr₂ (aq) ----------------> PbBr₂ (s) + Zn(CH₃COO)₂ (aq)

Where,

Pb(CH₃COO)₂ (aq) = Soluble salt (Completely dissociated)

ZnBr₂ (aq) = Soluble salt (Completely dissociated)

Zn(CH₃COO)₂ (aq)= Soluble salt (Completely dissociated) and

PbBr₂ (s)= Insoluble salt (Partially dissociated)

Complete ionic reaction is :

Pb²⁺ (aq) + 2 CH₃COO^- (aq) + Zn²⁺ (aq) + 2 Br^-(aq) ----------------> PbBr₂ (s) + Zn²⁺ (aq) +  2 CH₃COO^- (aq)

CH₃COO^- and Zn²⁺ are spectator ions, therefore they are cancelled in the net ionic equation.

So,

Net ionic equation is :

Pb2+ (aq) + 2 Br-(aq) ----------------> PbBr2 (s)
