Understand the Problem

The question asks to describe what is shown in the schematic at point (1), which represents the power supply in the electrochemical cell diagram.

Answer

The power supply at point (1) provides voltage, driving electrons from the copper electrode to the zinc electrode.

At point (1), the power supply provides the voltage needed for the non-spontaneous redox reaction to occur, driving electrons from the copper (Cu) electrode to the zinc (Zn) electrode.

Answer for screen readers

At point (1), the power supply provides the voltage needed for the non-spontaneous redox reaction to occur, driving electrons from the copper (Cu) electrode to the zinc (Zn) electrode.

More Information

In an electrolytic cell, a power supply is required because the redox reaction is non-spontaneous, meaning it needs an external source of energy to proceed.
