Voltaic/Galvanic Cells
This type of energy is produced by voltaic cells
What is electricity?
This item is needed for an electrolytic cell but NOT a galvanic one.
What is a power source (electricity)?
What is the periodic table?
What is reduction?
In a galvanic cell, oxidation does NOT occur at this electrode
What is the cathode?
In an operating electrolytic cell, oxidation occurs at this electrode
What is the cathode?
These atoms usually have only one oxidation state
What are Fluorine, Oxygen, and Hydrogen?
What half reactions are used to show
What is one part of a redox reaction?
This would be the anode in a cell with Na and Fe
What is Na?
This is the direction of electron flow in an electrolytic cell.
What is from the anode to the cathode?
The oxidation state of phosphorous in phosphoric acid.
What is +5?
This is the full redox reaction between Mn(s)/Mn2+ and Ni (s)/Ni2+
What is Mn + Ni2+ -> Ni + Mn2+?
The purpose of the salt bridge
What is ion exchange?
This reaction occurs when electrolytic cells are in water
The oxidation state of Cr in K4Cr2O72+
What is +6?
These are the half-reactions for a voltaic cell using Iron and Copper
What are
Fe -> Fe2++ 2e-
Cu2++2e- -> Cu
