Questions & Step-by-Step Solutions
In the reaction 2Fe²⁺ + Cl2 → 2Fe³⁺ + 2Cl⁻, what is being oxidized? (2021)
Step 1: Identify the reactants in the reaction: 2Fe²⁺ and Cl2.
Step 2: Determine the oxidation states of the elements in the reactants.
Step 3: Notice that Fe²⁺ has an oxidation state of +2.
Step 4: Observe that in the products, Fe³⁺ has an oxidation state of +3.
Step 5: Understand that oxidation is the process of losing electrons.
Step 6: Since Fe²⁺ goes from +2 to +3, it loses one electron.
Step 7: Conclude that Fe²⁺ is being oxidized to Fe³⁺.
Oxidation and Reduction – Oxidation involves the loss of electrons, while reduction involves the gain of electrons.
Half-Reactions – Understanding how to separate the oxidation and reduction processes into half-reactions can clarify which species is oxidized and which is reduced.
Redox Reactions – This question tests knowledge of redox reactions, where one species is oxidized and another is reduced.
