Solution: Suppose you have 5.05 g of powdered magnesium metal, 1.05 L of 2.00 M  potassium nitrate solution, and 1.05 L of 2.00 M  silver nitrate solution.Which one of the solutions will react with the magnesiu

Problem

Suppose you have 5.05 g of powdered magnesium metal, 1.05 L of 2.00 M  potassium nitrate solution, and 1.05 L of 2.00 M  silver nitrate solution.

Which one of the solutions will react with the magnesium powder?

Solution

We’re being asked to determine the solution that can react with magnesium: Potassium Nitrate or Silver Nitrate. We may disregard the volume and concentration of each since they are the same.


We have two possible reactions:

Mg (s)   +   KNO3 (aq)    →  

Mg (s)   +   AgNO3 (aq)  → 


Recall that the activity series gives us the relative reactivities of metals to oxidationmetals higher in the activity series are more reactive to oxidation and vice-versa.
