Problem: Explain how to Identify the reducing agent in a reaction of magnesium with oxygen.

FREE Expert Solution

We are being asked to identify the reducing agent in a reaction of magnesium with oxygen


To do so, we need to identify the change in oxidation state for each element in the reaction. 

Recall the mnemonic for redox reactions:

Loss Electrons Oxidation Reducing Agent

Gain Electrons Reduction Oxidizing Agent


This means the element that loses electrons/oxidized is the reducing agent. 


We will do the following steps:

Step 1: Write the overall balanced reaction

Step 2: Determine the oxidation state of reactants and products

Step 3: Determine the change in oxidation state
