Question

Gold ions, Au*(aq), can easily be made to precipitate out of a solution as gold metal. Simply

bring another metal into the solution, and this metal becomes the reducing agent in the
chemical change. Write the half-reaction to represent the change in gold as it precipitates out
of the solution.

Don’t need answer unless you want to solve:) I just need help with understanding the explanation

Answer 1

Step-by-step explanation:

gold is found very low down in the reactivity series thus is relatively unreactive. Metals found above gold in the series are more reactive compared to gold and thus is able to undergo a single displacement reaction, replacing gold in solution, which is then precipitated as a solid.
