A piece of zinc is placed in a solution containing silver ions. A reaction takes place. The silver ions are Ag⁺ ions, and zinc forms Zn²⁺ ions. Nitrate ions are also present in the solution but do not react.
State which metal is more reactive.
Write the ionic equation for the reaction.
Write the half equation for the oxidation of zinc.
Copper ions can also be displaced from solution. The half equation for the copper ions is Cu²⁺ + 2e⁻ → Cu.
State what the position of the electrons in this half equation shows about the copper ions.
