OXIDATION-Reduction :
OXIDATION-Reduction Fe Cu2+ Fe2+ Cu Fe(s) → Fe2+ + 2e- Cu2+ + 2e- → Cu(s)
Electron transfer reaction :
Electron transfer reaction Oxidation = donating electrons
Reduction = accepting electrons
Fe(s) → Fe2+ + 2e- Oxidation
Cu2+ + 2e- → Cu(s) Reduction
Fe(s) + Cu2+ → Fe2+ + Cu(s)
Solid Sodium Chloride :
Solid Sodium Chloride NaCl exists as a lattice structure as a solid.
It cannot conduct electricity as a solid as the ions cannot move.
It will conduct electricity if it is molten, but this requires enormous amounts of heat energy. Na+ Na+ Na+ Na+ Na+ Na+ Na+ Na+ Na+ Cl- Cl- Cl- Cl- Cl- Cl- Cl- Cl- Cl-
ELECTROLYTIC SOLUTIONS :
ELECTROLYTIC SOLUTIONS NaCl as a solution, will conduct electricity as the ions can easily move under the influence of an electric field. Positive electrode CATHODE Negativeelectrode ANODE + --
