Problem

Complete and balance:

CrBr₂(aq)+AgNO₃(aq) →

KCl(aq)+Pb(C₂H₃O₂)₂(aq) →

NaOH(aq)+(NH₄)₂SO₄(aq) →

Express your answer as a chemical equation. Enter NO REACTION if no reaction occurs. Identify all of the phases in your answer.

 

Solution

• Reactions are double displacement reactions, so the cation of one reactant will form a compound with the anion of the other reactant, and vice versa.

• For a), CrBr₂ dissociates as Cr²⁺ and Br^- while AgNO₃ dissociates as Ag⁺ and NO₃^-
