This activity aims to extend understanding of the Electrochemical Series by examining the behaviour of nitrates of metals in different positions of the ECS. Experiments and balanced equations show that compounds of metals high in the ECS are relatively stable whereas those low in the ECS are much less stable.

This item teaches:

• about the use of standard electrode potentials as an electrochemical series
• about the use of E values to predict the direction of redox reactions
• about the reactivity series
