Recap - Who Gave Electrons

Part of the Oxidation and Reduction section of Coddy's Chemistry journey. Lesson 10 of 27.

Challenge

A copper wire is hung in a colorless silver nitrate solution. Silver crystals grow on the wire and the solution slowly turns blue: Cu + Ag⁺ → Cu²⁺ + Ag. Name the element oxidized and the element reduced, choose the oxidizing and reducing agents, and count the electrons passed in the balanced equation.
