16.5—Different methods are used to measure standard electrode potentials of: i metals or non-metals in contact with their ions

Understand that different methods are used to measure standard electrode potentials of: i metals or non-metals in contact with their ions in aqueous solution ii ions of the same element with different oxidation numbers.

Use —different methods are used to measure standard electrode potentials of: i metals or non-metals in contact with their ions to connect the rule to the data and decision in the question.

This matters because —different methods are used to measure standard electrode potentials of: i metals or non-metals in contact with their ions determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —different methods are used to measure standard electrode potentials of: i metals or non-metals in contact with their ions to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Different methods are used to measure standard electrode potentials of: i metals or non-metals in contact with their ions is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
