Fe has greater ability to lose electron than Cu.so Fe lose electron and form iron sulphate and Cu take electrons and collect at cathod as Cu. That's why it displace the Cu by forming iron sulphates

adding sodium - it would ignite before it could react.

Fe is more reaction than copper and would displace it to combine with the sulphate ion, thereby separating copper.
