Electrolysis definition
Electrolysis definition
Uses electrical energy to drive non-spontaneous reactions
Cathode charge & reaction type
Cathode charge & reaction type
Negative electrode; reduction (gain of electrons)
Anode charge & reaction type
Anode charge & reaction type
Positive electrode; oxidation (loss of electrons)
Product at cathode in molten NaCl
Product at cathode in molten NaCl
Sodium metal (Na)
Product at anode in molten NaCl
Product at anode in molten NaCl
Chlorine gas ()
Which species reacts at cathode?
Which species reacts at cathode?
Strongest oxidising agent present
Which species reacts at anode?
Which species reacts at anode?
Strongest reducing agent present
Energy conversion in electrolytic cells
Energy conversion in electrolytic cells
Electrical energy to chemical energy
Why don't & react at anode?
Why don't & react at anode?
Already at maximum oxidation state, can't lose more electrons
Ions attracted to cathode
Ions attracted to cathode
Cations (positive ions)
