Summary
This document outlines the process of electrolysis, using electricity to split ionic compounds. It describes the reactions occurring at the electrodes, including reduction (gain of electrons) and oxidation (loss of electrons). The document also discusses different types of electrolysis, including aqueous and molten electrolysis and provides example half equations for the reactions.

**Electrolysis:** *"Using electricity to split ionic compounds."* -Positive ions(Cations) are attracted to,and moved towards the negative electrode (cathode) where they are discharged. -Negative ions (Anions)are attracted to and move towards the positive electrode (anode)where they discharge Discharged:When an ion gains electrons to reduce itself. Anion(+) → discharge and release electrons → Atoms(neutral).Ej e^-^ Cations(-)→ discharge and pick up electrons → Atoms (neutral)Ej e^-^  ^The\ compound\ you\ wish\ to\ split\ with\ electricity\ must\ be\ **molten(melt\ it)\ or\ dissolved**.^    **^[Half\ Equations\ for\ Electrolysis:]^** ^Explicacion:https://www.youtube.com/watch?v=W9ngXNxSyoo^ **^What\ are\ half\ equations\ used\ for?^** ^-To\ represent\ the\ reactions\ that\ happen\ at\ an\ electrode.^ **^Reduction^** ^-The\ gain\ of\ electrons^ **^Half\ Equations\ for\ reduction:^** - - - - **^How\ do\ these\ half\ equations\ show\ reduction?^** ^-They\ are\ gaining\ electrons.^ **^Half\ equations\ for\ oxidation:^** - - - - **^Oxidation:^** ^-Loss\ of\ electrons^ **^How\ do\ these\ half\ equations\ show\ oxidation?^** ^-They\ are\ losing\ electrons.^      **^[Aqueous\ Electrolysis:]^** ^**Aqueous**:A\ substance\ is\ dissolved\ in\ water\ to\ form\ a\ solution.^ ^Aqueous\ electrolysis\ uses\ less\ energy,as\ it\ doesn\'t\ melt\ it\ but\ the\ **product\ is\ different**.^
