Question

Predict if a reaction would occur when solutions of 0.1 M Al(NO3)3 and 0.1 M KI are combined. Explain your reasoning, and, if you predict a reaction will occur, include the net ionic equation for the reaction.

Answer 1

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.
