What is the oxidized substance in the following reaction? fe + 2hcl → fecl2 + h2 a. fe b. hcl c. fecl2 d. h2

The Fe increases its oxidation number from 0 to +2,  it means that electrons are lost, therefore the Fe is the reducing agent and is the oxidized substance.

Explanation:

1. First write down the chemical equation:

2. Then determine the oxidation numbers for each compound:

3. Write the elements that change its oxidation number:

-

→  

The H decreases its oxidation number from +1 to 0, it means that electrons are gained, therefore the H is the oxidizing agent and is the reduced substance.

-

→  

The Fe increases its oxidation number from 0 to +2,  it means that electrons are lost, therefore the Fe is the reducing agent and is the oxidized substance.
