Electrochemistry
• the relationship between the flow of electric current and chemical changes– ElectrolysisElectrolysis
• changes electrical energy into chemical energy– charging a car battery– electroplating a metal
• involves reactions with partial gain/loss of electrons
– Electrochemical CellElectrochemical Cell• changes chemical energy into electrical energy
– dry cells running iPod, cell phone etc
• involves reactions with complete gain/loss of electrons
