Answer:
Possibility of a single replacement reaction
Explanation:
The activity series of element can be used to predict the possibility of a single replacement reaction.
- A single replacement reaction is one in which one substance is replacing the other.
- The replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in solution falls into this category of reactions.
- The relative position of the two elements in the activity series provides the driving force for this kind of reaction.
- If the element to replace the other is more reactive, the reaction will occur.
- If it is less reactive, the reaction will not occur.
