# Electronegative - Electropositive atoms can attract ions?

Well I was just wondering how a copper-zinc battery works, with electrolyte an equilibrium of water and NaOH. It says that NaOH is dissolved (I understand that) into water forming H$$_4$$O$$_8$$Na+ ions and H$$_4$$O$$_8$$OH- ions. But how do those ions get attracted towards the anode and the cathode of the battery (H$$_4$$O$$_8$$Na+ attracted to cathode, H$$_4$$O$$_8$$OH- attracted to the anode)? Zinc molecules and Copper molecules are not dipole molecules.

• You wouldn't use NaOH in a zinc-copper battery. That would form insoluble zinc hydroxide and gum up your battery. Are you sure you mean NaOH and not NaCl? – John Rennie Jan 22 at 14:38
• Yes sorry NaCl is the salt I use unstead of NaOH which is a base – Max Destiny Jan 22 at 15:09
