Finding major species in aqueous solutions!

  1. Mar 8, 2005 #1
    Which of the following are correct statments ?


    a) In an aqueous solution of NH4Cl, H2O, NH4+ and Cl-are the major species present

    b) In an aqueous solution of NaCH3CO2, H2O, Na+ and HCH3CO2 are the major species present

    c) In an aqueous solution of HCN, H2O, H3O+ and CN- are the major species present

    d) In an aqueous solution of HNO3, H2O, H3O+ and NO3- are the major species present

    e) In a solution of CH3CO2H and NaOH, Na+ is a spectator ion

    I know a should be right since those are ions, but dont know about the rest. Help

    You should look at the Ka values for all species and decide, whether acids are dissociated or not. That's the main point.

    Try BATE for these calculations - while you should be able to make them by yourself it can help check the results :wink:
