{{id}} {{{paragraph}}}
1. Electrolysis - The Electrolytic Cell Electrolysis : The decomposition of some substance by means of an electric current. Electrolytic Cell: A cell that requires electrical energy to cause nonspontaneous oxidation-reduction reactions to occur. it utilizes an external source of electrical energy. it forces electrons to flow in the opposite direction by applying a voltage greater than the cell potential. it converts electrical energy into chemical energy Voltaic Cell Electrolytic Cell Spontaneous redox Nonspontaneous redox reaction releases energy reaction absorbs energy to drive it Anode = oxidation = negative Anode = oxidation = positive (negative charge supplied by reaction) Cathode = reduction = negative Cathode = reduction = positive (negative charge supplied externally).
