Net ionic eqaution

  1. Oct 4, 2007 #1

    elect "True" or "False" to indicate whether or not the stated reaction (or "no reaction") correctly corresponds to the expected observation in each case.


    Sodium bromide and hydrochloric acid; Na+(aq) + Cl-(aq) --> NaCl(s)

    Copper(II) sulfate and ammonium carbonate; Cu2+(aq) + CO32-(aq) --> CuCO3(s)

    Calcium acetate and sodium carbonate; Ca2+(aq) + 2C2H3O2-(aq) --> Ca(C2H3O2)2(s)

    Magnesium chloride and sodium hydroxide; Mg2+(aq) + 2OH-(aq) --> Mg(OH)2(s)

    Ammonium sulfate and barium nitrate; No reaction occurs.



    can u plz help me in this Select "True" or "False" to indicate whether or not the stated reaction (or "no reaction") correctly corresponds to the expected observation in each case.

    for each equation write the molecular, ionic and net ionic equation for each double replacement (aka methathesis reaction)

    Ex.
    NaBr( ) + HCl( )---> NaCl( ) + HBr( )
    look up the solubilities of the reactants and products --- are they (aq) or (s) ?
    Ionic reaction:
    anything that is aq, can be written as dissociated like Na+(aq) + Br-(aq)
    if everything is the same on the left and the right, all cancels, no net ionic
    If something has (s), cannot dissociate, there will be a net ionic equation

    so working out your own solution for the net ionic and compare with what the given statements are and you can determine if the statements are true or false
