The cathode is the electrode where reduction (gain of electrons) takes place (metal-B electrode); in a galvanic cell, it is the positive electrode, as ions get reduced by taking up electrons from the electrode and plate out (while in electrolysis, the cathode is the negative terminal and attracts positive ions from the ...

Is cathode positive or negative in galvanic cell?

In a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. This seems reasonable as the anode is the source of electrons and cathode is where the electrons flow.

Why cathode is positive in galvanic cell?

In a galvanic cell, electrons will move in to the anode. Since electrons carry a negative charge, then the anode is negatively charged. Same thing with the cathode. It's because the protons are attracted to the cathode, so it's mainly positive, and therefore is positively charged.
