Homework Help: Balancing equations

  1. May 20, 2007 #1
    What are the missing coefficients for the equation below?

    Al2(SO4)3 + KOH ---> Al(OH)3 + K2SO4

    a.) 1,6,2,3
    b.) 2,12,4,6
    c.) 1,3,2,3
    d.) 4,6,2,3

    I think my problem is whether or not to keep the SO4 together, or break it apart to sulfur and oxygen?

    For counting purposes, keep the OH and SO4 together. Then look at the coefficients of the metal ions to help you balance the equation.
