Negative

Electrode charge of a voltaic cathode cell?

Positive

Electrode charge of a electrolytic anode cell?

Positive

Electrode charge of a electrolytic cathode cell?

Negative

Salt bridge function

Physical separation but electrical continuity from anodes and cathodes

Oxidation always occurs at the

Anode

Reduction always occurs are the

Cathode

How to draw beakers?

Anode reaction on left and cathode reaction on right

Primary cell

Are not reuseable and convert chemical energy to electrical energy

Secondary cell

Are rechargeable and have reversible chemical reactions to input and withdrawal chemical energy.

If you have charging equation how do you find discharging equation?

Reverse the reactants and the products in the charging equation
