Oxidation & Reduction
What term describes the gain of electrons?
Reduction
Where does oxidation occur in a galvanic cell?
Anode
Where does the loss of electrons occur in a redox reaction?
Oxidation
Where does reduction happen in a galvanic cell using copper and zinc?
Cathode
In the redox reaction Fe³⁺ + e⁻ → Fe²⁺, what process is taking place?
Reduction
What component balances ion buildup in a galvanic cell?
Salt bridge
What do you look at to determine if an element has been oxidized or reduced?
Oxidation Numebrs
What are the two agents that cause electron transfer in redox reactions?
Oxidizing and reducing agents
Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s)
Which element is being oxidized, and which is being reduced?
Zinc is oxidized; copper is reduced.
In a galvanic cell using the reaction:
Mg(s) + Ag⁺(aq) → Mg²⁺(aq) + Ag(s)
Magnesium is the anode; silver is the cathode.
