    ok, I don't know which chapter to read to remember this. I am having problems remeber how to deal with dissociation like this one (I know easy!!! but I can't do it...)

    Mg(OH)2 (s) ↔ Mg2+(aq) + 2OH- (aq)
    Why is Mg2+ and 2OH- I can't remember the rules to follow and I don't know which chapter to look to refresh my memory....

    Thanks in advance

    Maybe it is time to review the basics. Any gc textbook should have the info you need.
