cations are positive or negative?

what about anions?

and in electrolytic cell anode is negative and cathode is positive ?am i right

and which other cell is there in which there is anode positive and cathode negative??

Cations +ve like Na+

Anions -ve like Cl-

For electrochemical cells remenber 1 thing only

LOAN- Left Oxidation Anode Negative.

This implies that Cathode is +ve in electrochemical cells.

In electrolytic, polarity is opposite( Anode is + and Cathode is -ve) 

Cations are +ve e.g. Na⁺ , Cu²⁺

& anions are -ve. e.g. Cl^- , O^2-.

Cathode is -ve & anode is +ve.

i.e. at cathode,reduction takes place, whereas at anode, oxidation takes place.

In electrolytic anode is +

In electrochemical anode is -ve.
