Electrons flow TOWARD the: {Ans: - positive electrode}Properties of a Salt Bridge: {Ans: - complete the circuit, allowing the reaction to occur - prevent contents of the half cells from mixing - maintain charge balance by allowing cations and anions in the salt bridge to flow into half cells - ions from the salt bridge DO NOT participate in the redox reactions}Reduction {Ans: }Oxidation {Ans: - when electrons are LOST}Electrolytic Cells {Ans: - electrochemical cells - nonspontaneous cell - Delta G is POSITIVE - Ecell (cell potential) is NEGATIVE - consume energy - NEED a power source - used to produce different elements - have Anode (where oxidation takes place) and Cathode (where reduction takes place) - Anode (+) will be on LEFT - Cathode (-) will be on RIGHT}True statements about ELECTRODES {Ans: - the cathode is the electrode at which reduction occurs - the anode can be positive or negative - electrodes are surfaces on which oxidation or reduction half reactions occur - electrodes that dont react are INERT CELLS}Oxidation {Ans: }True statements about Salt Bridge: {Ans: - allows electrical contact between the two solutions in the half cells -
