Ionization of Zinc in galvanic cells

  1. Dec 1, 2013 #1
    what exactly ionizes zinc in the galvanic cell or the daniell cell ?
    i mean zinc atoms in the galvanic cell are ionized into Zn ++ and 2 e- .
    then the electrons move through the conductor to the copper bar , my question is why does zinc ionize when connected in a battery ? when the circuit is turned off , the ionization stops , why's that ?

    What happens in the other half cell?

    So there is a charge transfer between both half cells?
