Electrolysis - -Separating a ionic compounds using Reason solid ionic compounds cannot conduct - -
electricity The ions have a fixed position and cannot move


anion - -negatively charged ion Reason molten substances can conduct - -The ions
are free to move

anode - -positive electrode
Equation to show what happens at cathode - -Mg2+
+ 2e- -> Mg
cation - -positively charged ion

Equation to show what happens at anode - -2Cl- ->
cathode - -negative electrode Cl2 + 2e-
