Acid-Base reaction help

  1. Apr 16, 2010 #1
    1.The problem statement, all variables and given/known data

    1.Write net Bronsted equations that show the acid-base reactions of common household items. For polyprotic species (vitamin C, lemon juice, and baking powder), please show only one proton transfer. Remember that spectator ions are not included.

    A)Sodium Hypoclorite and H2C6H6O6

    B)Sodium Carbonate and HC2H3O2


    Another question:

    2.Chemical formula and conjugate acid of tums antacid (calcium carbonate) with a pH of 8.5 when reacted with H20

    Chemical formula for lithium hydrogenphosphate with a pH of 9.7 and conjugate acid when reacted with water


    2. Relevant equations

    Acid + Base -> Conjugate Base + Conjugate Acid


    3. The attempt at a solution

    A) H2C6H6O6 + NaClO -> HC6H6O6^1- + NaClO^1+

    I got the acid and conjugate base right, but its not taking NaClO or NaOCl as Sodium carbonate.

    B) HC2H3O2 + Na2CO3 -> C2H3O2^1- + Na2CO3^1+

    once again, not taking the base or conjugate acid. I don't know why Na2CO3 is not right for sodium carbonate...

    2. Tried CaCO3 for calcium carbonate and it did not like that answer.

    Tried H2LiPO4 for lithium hydrogenphosphate and no luck.

    Any help appreciated...

    First of all - some of these substances are already dissociated before acid/base reactions start. For example sodium carbonate dissociates to Na+ and CO32- - and Na+ is just a spectator.
