Galvanic Cells

What happens in redox reaction

electrons are transferred

What kind of energy is released in a spontaneous chemical reaction

electrical energy

What happens if OA and RA are in contact in redox reations

electrical energy turns into thermal energy and is released to enviornment

How is energy harnessed in redox reactions

seperating OA and RA forcing electron transfer

Why does seperating OA and RA help harness electrical energy

it forces electron

What does a galvanic cell consist of

electrode, electrolyte, salt bridge

Electrode

solid electrical conduuctor in contact with electrolyte solution

Electrolyte

solution of ions in contact with electrode

Salt Bridge

contains a salt solution which connects 2 half cells

function of salt bridge

path for ions to flow to each half cell to prevent charge build up/ polarization

Inert electrodes

provide surface for redox rxn to occur but not participate in the redox reaction
