Oxidation and Agents question with out answer

What is an oxidizing agent?

• A substance that loses electrons during a reaction.

• A catalyst that speeds up oxidation without being consumed.

• A compound that only reacts with acids.

• An oxidizing agent is a substance that promotes oxidation by gaining electrons.

Name one common oxidizing agent used in laboratories.

• Potassium permanganate

• Acetic acid

• Hydrochloric acid

• Sodium chloride

What is the oxidation state of oxygen in most compounds?

How do you determine the oxidation state of an element in a compound?

• Oxidation states can only be determined through experimental data.

• The oxidation state is always zero in compounds.

• The oxidation state is the same as the atomic number of the element.

• The oxidation state of an element in a compound is determined by applying oxidation state rules and ensuring the sum equals the compound's charge.

What is the oxidation state of hydrogen in most compounds?

• +2

• -1

• +1

• 0

What happens to the oxidation state of an element when it acts as an oxidizing agent?

• The oxidation state of the element decreases.

• The oxidation state of the element fluctuates randomly.

• The oxidation state of the element remains the same.

• The oxidation state of the element increases.

List two examples of strong oxidizing agents.

• Calcium carbonate

• Potassium permanganate, Hydrogen peroxide

• Sodium chloride

• 0

How does the oxidation state of an element change during a redox reaction?

• The oxidation state remains constant during a redox reaction.

• The oxidation state is irrelevant in redox reactions.

• The oxidation state of an element increases when it loses electrons and decreases when it gains electrons.

• The oxidation state decreases when it loses electrons and increases when it gains electrons.
