Redox Flashcards
A reduction oxidation reaction involves the transfer of
Electrons
Reductions is the
Gain of electrons and decrease of the oxidation number
Oxidation is the
Loss of electrons and increase of the oxidation number
The number of electrons lost is equal to
Number of electrons gained
Double replacement reactions are
Never redox reaction
Single replacement reactions are
Always redox reaction
An electrochemical cell can either be
Voltaic or electrolytic
In an electrochemical cell oxidation occurs at the
Anode
In an electrochemical cell reduction occurs at the
Cathode
A voltaic cell spontaneously converts
Chemical energy to electrical energy
An electrolytic cell need what to make a chemical change?
Energy
What is electrolysis
When an electrolytic cell needs energy to make chemical changes
What is electrolysis
When an electrolytic cell needs energy to make chemical changes
