In an electrolytic cell WHAT energy is used to force a WHAT chemical reaction to occur ( opposite of a WHAT cell)
In an electrolytic cell ELECTRICAL energy is used to force a NON-SPONTANEOUS chemical reaction to occur ( opposite of a VOLTAIC cell)
These reactions have a WHAT (E°net)
NEGATIVE
Commonly used to WHAT (eg, gold, silver, bronze, chromium), WHAT and split compounds into WHAT (eg. H2, O2, Cl2)
Commonly used to ELECTROPLATED METALS (eg, gold, silver, bronze, chromium), RECHARGE BATTERIES and split compounds into USEFUL GASES (eg. H2, O2, Cl2)
The electrolytic cell is hooked up to a WHAT (instead of load or external circuit) so the flow of electrons is WHAT
The electrolytic cell is hooked up to a BATTERY or POWER SOURCE (instead of load or external circuit) so the flow of electrons is “PUSHED“ by an OUTSIDE FORCE
The CATHODE of the electrolytic cell is connected to the WHAT if the battery therefor is WHAT
The CATHODE of the electrolytic cell is connected to the ANODE if the battery therefor is NEGATIVE
The ANODE of the electrolytic cell is connected to the WHAT if the battery therefor is WHAT
The ANODE of the electrolytic cell is connected to the CATHODE if the battery therefor is POSITIVE
Voltaic cells:
What to what energy
Cathode (WHAT), anode (WHAT)
Usually contains a WHAT
E°net is WHAT (WHAT)
Has a WHAT
Electrolytic cells
What to what energy
Cathode (WHAT), anode (WHAT)
Usually doesn’t contains a WHAT
E°net is WHAT (WHAT)
Has a WHAT
Both
Electrons flow from the WHAT to the WHAT
Oxidation at the WHAT
Reduction at the WHAT
Cations migrate to the WHAT
Anions migrate to the WHAT
Voltaic cells:
CHEMICAL to ELECTRICAL energy
Cathode (POSITIVE), anode (NEGATIVE)
Usually contains a POROUS CUP or SALT BRIDGE
E°net is POSITIVE (SPONTANEOUS)
Has a VOLTMETER or EXTERNAL LOAD
Electrolytic cells
ELECTRICAL to CHEMICAL energy
Cathode (NEGATIVE), anode (POSITIVE)
Usually doesn’t contains a POROUS CUP or SALT BRIDGE
E°net is NEGATIVE (NON-SPONTANEOUS)
Has a POWER SUPPLY
Both
Electrons flow from the ANODE to the CATHODE
Oxidation at the ANODE
Reduction at the CATHODE
Cations migrate to the CATHODE
Anions migrate to the ANODE
