What is the direction of anion movement in an electrochemical cell? O Anode to cathode through the salt bridge OAnode to cathode in the external circuit Anode to cathode through the porous cup Cathode to anode through the salt bridge Cathode to anode through the external circuit

What statement is true?     an electrolysis takes place in voltaic cell     an electrolysis requires an electric current to drive a nonspontaneous reaction     during an electrolysis the reduction is observed at the anode     an electrolysis takes place in galvanic cell

Match the components of an electrochemical cell with the appropriate function. Words: Voltmeter Cathode Anode Porous Bridge Electrode Definitions: Allows flow of ions that neutralize the charge buildup Measures the difference in electric potential as voltage Conductive surfaces through which electrons can enter or leave the half-cells Electrode where the reduction takes place Electrode where oxidation takes place

When creating an electrochemical cell, why is it important to prevent the reactants from any direct contact?
