Interpretation: The metal which is more easily oxidized needs to be identified from lead or calcium.
Concept Introduction: In an
In oxidation, the loss of electrons takes place by an element and its oxidation state increases Similarly in reduction, the gain of electrons takes place by an element. Here, the oxidation state of the element decreases.
Explanation of Solution
The given elements are lead and calcium.
The reduction electrode potential for lead and calcium is -0.13 V and -2.87 V respectively. The element with more reduction potential and be easily reduced.
Here, the reduction potential for lead is more thus, lead can undergo reduction more easily. Thus, the metal which is more easily oxidized will have a lower reduction electrode potential. Therefore, calcium is more easily oxidized.
