Answer:
The reaction is impossible
Explanation:
Potassium is above aluminum in the electrochemical series hence it cannot be displaced by aluminum in a double decomposition reaction.
A double decomposition (often shown by a net ionic equation) is possible if and only if the reaction leads to the formation of an insoluble precipitate.
Such a reaction cannot occur here because the redox potential of potassium is far more negative than that of aluminum hence the reaction is impossible.
The reaction between 0.1 M Al(NO₃)₃ and 0.1 M KI is not feasible.
Why the reaction does not occur?
