Homework Help: NaNo_3 dissolved in NaCl saturated solution

  1. Jan 13, 2009 #1
    1. The problem statement, all variables and given/known data
    Explain why sodium chloride will precipitate from a saturated aqueous solution when sodium nitrate is dissolved in this solution.

    2. Relevant equations
    no equations.

    3. The attempt at a solution

    The saturated NaCl solution cannot dissolve any more sodium, so as NaNo3 dissolves sodium must precipitate. It reacts with chlorine to precipitate as NaCl.
    Why does it do this?

    Any help would be appreciated.
