If y is an oxidizing agent that reacts with a reducing agent, Z, which of the following is correct?
Y increases in oxidation number
Y becomes reduced
Z loses protons
Z gains protons
Explanation
An oxidizing agent is reduced in a chemical reaction, meaning it gains electrons and its oxidation state decreases. An oxidizing agent, also known as an oxidant or oxidizer, is a substance that causes oxidation by accepting electrons from another compound, called the reducing agent. This process is called reduction, and it makes the oxidizing agent more negative.
