Q - Aluminum metal reacts with zinc(II) ion in an aqueous solution by the following half-cell reactions:
Al(s) → Al3+(aq) + 3e−
Zn2+(aq) + 2e− → Zn(s)
Predict the potential of the cell under standard conditions.
Predict whether the reaction will occur spontaneously, or whether a source of electricity will be required for the reaction. Justify your answer.
In terms of the metals involved, predict the direction electrons will flow in the reaction.
Predict which electrode will lose mass and which will gain mass.
