    1: Don't double post.
    2: This is, as I hope you know, an acid reaction (not sure of the right words in english). [tex]{SO_4}^{++}[/tex] is an acid, [tex]OH^-[/tex] (which appears when dissolving NaOH) is a very strong base. They will obviously react. Think again, and maybe you'll find it.

    What is SO4++? I think you meant SO42-, which is a conjugate base and not an acid. SO42- will NOT react with OH- because both want to accept a hydrogen ion. It WILL react with H2O, however.

    First, I'd start out by writing out the ions dissociated. KNO3 is soluble, NaOH is a strong base so it will dissociate, and MgSO4 is soluble in water. Then think which two ions will go together to form a precipitate.

    Then think about what will happen when the SO42- reacts with H2O. Let's see what you can come up with :smile:.
