Question

A magician arrives in a village and claims that he has a magic potion on sale that can transform copper objects to silver. For the demonstration, he asks the villagers to give him a copper object, which he suspends in his magic potion. After an hour, he takes out the object, which seems to be transformed to 'silver.' Can you tell what the magician's magic potion could be and explain the principle behind the trick? (hint: recall the activity series of metals)

Answer 1
