Write the net ionic equation for the reaction that occurs,if any,when gold is placed in a solution of hydrobromic acid.Hydrogen gas is above gold in the activity series.What are the products?

Question

Quizplus · Accepted Answer

Since hydrogen is above gold in the activity series, it will displace gold from the hydrobromic acid to form hydrogen gas and aqueous gold(III) bromide. The net ionic equation is:
2 H+(aq) + 2 Br-(aq) + Au(s) → H2(g) + AuBr2(aq)
However, the equation has no spectator ions, so it's already a net ionic equation. Therefore, the correct answer is E, which indicates that there is no reaction.
