==Key Stage 4==
===Meaning===
[[Electrolysis]] is a process in which a a [[liquid]] [[Ionic Compound|ionic compound]] is [[Decompose (Chemistry)|decomposed]] by passing an [[Electrical Current|electrical current]] through it.
===About Electrolysis===
: In [[electrolysis]] two [[electrode]]s (an [[anode]] and a [[cathode]]) are placed in either a [[molten]] or [[aqueous]] [[Ionic Compound|ionic compound]].
: The [[Positive Ion|positive ions]] are [[attracted]] to the [[Negative Charge|negative]] [[electrode]] ([[cathode]]) and the [[Negative Ion|negative ions]] are [[attracted]] to the [[Positive Charge|positive]] [[electrode]] ([[anode]]).
: When the [[Negative Ion|negative ions]] reach the [[anode]] they lose [[electron]]s to become [[atom]]s or [[Neutral (Charge)|neutral]] [[compound]]s.
: When the [[Positive Ion|positive ions]] reach the [[cathode]] they gain [[electron]]s to become [[atom]]s. However, in [[aqueous]] [[solution]] if the [[metal]] [[ion]]s are more [[reactivity|reactive]] than [[Hydrogen]] then [[Hydrogen]] [[gas]] will be [[product|produced]].
