Redox Quizizz

What is a redox reaction?

• A reaction where both reactants get reduced.

• A reaction where both reactants get oxidized.

• A reaction that involves a transfer of electrons between reactants.

• A reaction that involves the combustion of at least one reactant.

What is reduction?

• It is the gain of electrons.

• It is the loss of electrons.

• It is the creation of electrons.

• It is the destruction of electrons.

What is oxidation?

• It is the gain of electrons.

• It is the loss of electrons.

• It is the creation of electrons.

• It is the destruction of electrons.

What is a reducing agent?

• It is the species that gets reduced -- gains electrons.

• It is the species that gets oxidized -- loses electrons.

• It is the species that creates electrons.

• It is the species that destroys electrons.

What is an oxidizing agent?

• It is the species that gets reduced -- gains electrons.

• It is the species that gets oxidized -- loses electrons.

• It is the species that creates electrons.

• It is the species that loses electrons.

What is a galvanic (voltaic) cell?

• It is a cell that destroys electrons on one side and creates electrons on the other side.

• It is a cell that contains only one metal bar and one aqueous ion solution.

• It is a type of battery that drives a redox reaction when electricity is applied.

• It is a type of battery that generates an electrical current from redox reactions.

What is an anode?

• It is the electrode where oxidation takes place.

• It is the electrode where reduction takes place.

• It is an aqueous solution containing an electrode.

• It is the salt bridge that connects half-cells.

What is a cathode?

• It is the electrode where oxidation takes place.

• It is the electrode where reduction takes place.

• It is an aqueous solution containing an electrode.

• It is the salt bridge that connects half-cells.

Electrons always flow from

• cathode to anode

• anode to cathode

An iron nail is put into a solution of copper nitrate, iron is above copper in the activity series of metals, what will happen?

• iron will be reduced
• bubbles of oxygen gas will form on iron nail
• the iron nail will become copper plated
• no reaction occurs
