Main Question or Discussion Point

Hi!

If I dissolve MgCl2 in distilled water, will it form into [Mg++] + [Cl-] + [-Cl] ?
or [Mg++] + [Cl2--]? -And Why? is it because of stability constants?

-Also Are there any intermediate steps in the process?

Similarly, If I dissolve MgSO4 in distilled water, without electric currents or temperature / pressure changes,
it will dissolve into Mg + SO4, right? or will it go into H2SO4 + MgO, and then MgO + H2O will go into Mg(OH)2
and then Mg(OH)2 + H2O = Mg2 + OH- ??

-Please help!!

Thank you for your insights and valuable help!! I can't figure this, as foolish as it is!

I have at least never heard of Cl2 double anion. The chlorine is not bonded to magnesium kation as Cl2, but as individual Cl-atoms, and in aqueous solution MgCl2 will dissolve into Mg++ and 2 Cl-.

This is the case for all salts as far as I know.

Thank you very much, and what about the MgSO4 question?

Thanks in advance to anyone providing insights! I know for you it may be silly, but for me its a important question! =D
