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.What is the net ionic equation that describes this reaction?

FREE Expert Solution

We’re being asked to write the net ionic equation for the reaction in a mixture of powdered magnesium metal, potassium nitrate solution and silver nitrate solution.


We’re going to determine the spectator ions using the following steps:

Step 1. Write the overall balanced reaction
Step 2. Write the total or full ionic equation
Step 3. Identify the spectator ions


Step 1. Write the overall balanced reaction

Reactants:

powered magnesium metal → Mg(s)

▪ Mg → Group 2A → +2 charge → Mg2+
