Question

Complete ionic equation                                                  CaBr2(aq)+2AuClO4(aq) → 2AuBr(s)+Ca(ClO4)2(aq)

The molecular equation you determined in Part B is shown above for your convenience. Examine each of the chemical species involved to determine the ions that would be present in solution. Be sure to consider both the coefficients and subscripts of the molecular equation, and then write this precipitation reaction in the form of a balanced complete ionic equation. Express your answer as a chemical equation including phases.

Answer 1

molecular equation :

CaBr2(aq)+2AuClO4(aq) -----------> 2AuBr(s)+Ca(ClO4)2(aq)

complete ionic equation :

Ca²⁺ (aq) + 2 Br^- (aq) + 2 Au⁺ (aq) + 2 ClO₄^- (aq) -------------> 2 AuBr(s) + Ca²⁺ (aq) + 2 ClO₄^- (aq)
