Standard Electrode Potential (6)

Atoms or ions with a more negative or less positive standard electrode potential value, E° (2)

Easier to undergo oxidation reaction

Atoms or ions with a more negative or less positive standard electrode potential value, E° (3)

A stronger reducing agent

Way to identify the oxidising agent and reducing agent reaction that occur between copper, Cu and silver nitrate, AgNO3 (1)

The standard electrode potential value, E0 is arranged from the most negative to the most positive. Cu2+ + 2e− ⇌ Cu E° = + 0.34 V Ag+ + e− ⇌ Ag E° = + 0.80 V

Way to identify the oxidising agent and reducing agent reaction that occur between copper, Cu and silver nitrate, AgNO3 (2)(i)

When E° value of Cu is more negative or less positive than E° of Ag, copper, Cu is a stronger reducing agent compared to silver, Ag

Way to identify the oxidising agent and reducing agent reaction that occur between copper, Cu and silver nitrate, AgNO3 (2)(ii)

When E° value of Cu is more negative or less positive than E° of Ag, copper, therefore, copper atom, Cu has a greater tendency to release electrons to form copper(II) ions, Cu2+
