19.1.1

Describe the standard hydrogen electrode.

2

19.1.2

Define the term standard electrode potential.

1

19.1.3

Calculate cell potentials using standard electrode potentials.

2

19.1.4

Predict whether a reaction will be spontaneous using standard electrode potential values.

3

19.2.1

Predict and explain the products of electrolysis of aqueous solutions.

3

Explanations should refer to values, nature of the electrode and concentration of the electrolyte. Examples include the electrolysis of water, aqueous sodium chloride and aqueous copper(II) sulfate.

Aim 7: Virtual experiments can be used to demonstrate this.

19.2.2

Determine the relative amounts of the products formed during electrolysis.

3

The factors to be considered are charge on the ion, current and duration of electrolysis.
