Electrochemical Cell Flashcards
what accepts electrons
strongest oxidising agent
what donates electrons
strongest reducing agent
How to harness the flow of electrons between 2 redox system
Use electrochemical cells
what is the function performed by the salt bridge
Allows ions to flow between cells without solutions mixing, ∴ completing the circuit
what is the function performed by the electrolyte in a fuel cell
Allows ions to flow between cells without solutions mixing, ∴ completing the circuit
why does the H electrode have an electrode potential of 0
it is the standard, where all other values are measured
E⦵ =
(+)-(-)
how to determine feasibility
if (+), it is feasible
what is the electrode made of
platinised electrode
- unreactive
- finely ground ∴ higher surface area
what are the components of electrochemical cells
- high resistance voltsmeters
- salt bridge
- Two 1mol/dm^3 solutions
what is the salt bridge made of
saturated potassium nitrate
