this is so good Abs! i think you spelt electrolysis wrong though ;)

ELECTROLYSISThe breakdown of an ioniccompound into its elementsby use of electricitydecomposition of anelectrolyte bypassage of an electriccurrent= electrolosisElectrolyte= substancewhich will conductelectric currentMust be molten OR dissolved inwaterThe electrolyte is broken down byelectricity passed through anELECTRODE.Positiveelectrode=ANODENegativeelectrode=CATHODEIn solids= chargecarrier- electronsIn liquids= chargecarrier- ionsElectrolyte MUST bemolten/solution to conduct.thus, ions are free to moveIonic compound=positive ions (atomswhich lost negativeelectrons) and negativeions (atoms which gainednegative electrons)2 ways to split up ionsTake alot to break astrong ionic bond in aGIANT structure- but withenough energy willmelt and becomemoltenDissolve in water.eg; Zinc Chlorideelectrolysed= Zincmetal+Chlorine gasElectrolysis can only occur on FREE substancesNegatively charged ions attracted herePositively charged ions attracted hereOpposites attract1.
