1.) I think your refering to the electrolysis of conc. NaCl. The membrane allows Na+ ions to move to the right of the cell to meet OH- ions
2.) Its both. In an exam you give any as your answer. The Zn displaces Cu from its salt at the same time losing 2 electrons to Cu2+ to form Cu metal.
3.) ill be back...
