Can anyone explain me this question

  1. Oct 20, 2006 #1
    Which is the acid salt of which the aqueous solution is basic?
    [tex] {\rm{1) NaHSO}}_{\rm{4}} [/tex]
    [tex]{\rm{2) Na}}_{\rm{2}} {\rm{So}}_{\rm{4}} [/tex]
    [tex] {\rm{3) NaHCO}}_{\rm{3}} [/tex]
    [tex]{\rm{4) Na}}_{\rm{2}} {\rm{CO}}_{\rm{3}} [/tex]
    [tex]{\rm{5) Mg(OH)}}_{\rm{2}}[/tex]
    [tex]{\rm{6) MgCl(OH)}} [/tex]

    can anyone explain what is acid salt and what the word "aqueous solution is basic" mean

    well...havent you done acids and bases in chemsitry yet? if not, by this question, im assuming your suposed to have so read up on it in your text book. its basically asking which of those has an acid salt which is basic, which imo is a pretty silly question but anyway

    i think

    No, not unless you show some work on how you arrived on yours, right or wrong, its the policy on Physics Forums.

    please check whether my explanation is right or wrong
    (1)(3)(6)
    unsusure about Mg(OH)2.if Mg(OH)2 is aqueous,then it should be one of the answers.
    NaHSO4=Na+HSO4
    Na somehow increase the concentration of OH- and HSO4 somehow increase the concentration of H+.(sorry by which way I cannot remeber)

    its basically asking which of those is basic in solution. its a stupidly worded question.
