Balancing Chemical Equation

  1. Sep 30, 2009 #1
    The problem statement, all variables and given/known data
    I am to balance the following equation:
    Al(OH)41-(aq) + H2SO4(aq) ---> Al(OH)3(s) + H2O + SO42-

    The attempt at a solution

    Al(OH)41-(aq) + H2SO4(aq) ---> Al(OH)3(s) + 3/2H2O + SO42-

    The bolded part above is all I could add to the equation, but I now need to balance the oxygen. This is where I am stuck. Any help is appreciated.

    It is not only oxygen, there are more problems with the equation - charge is not balanced.

    Al(OH)4- loses OH-, H2SO4 loses 2H+. Try to start from here.
