Description
This task is a typical "discovery-style" activity where the experimental results allow to compare the metal chemical reactivity and eventually come up with the idea how the given metals differ in activity.
The student has to determine the order of metals in the electrochemical series by performing displacement reactions between metals (Cu, Zn, Ag, Fe) and the corresponding salt solutions.
The system automatically checks whether the student was correct in their metal sequencing.
